7.1 Legal, moral, ethical and cultural implications

7.1 Legal, moral, ethical and cultural

implications

Key terms

Legal – relating to, or permissible by, law.

Morality – an understanding of the difference between

right and wrong, often founded in personal beliefs.

Ethics – moral principles governing an individual’s or

organisation’s behaviour, such as a code of conduct.

Culture – the attitudes, values and practices shared by

a group of people/society.

Intellectual property rights – rules governing an

individual’s ownership of their own creations or ideas,

prohibiting the copying of, for example, software

without the owner’s permission.

Privacy – the right to keep personal information and

data secret and for it to not be unwillingly accessed or

shared through, for example, hacking.

Plagiarism – the act of taking another person’s work

and claiming it as one’s own.

BCS – British Computer Society.

IEEE – Institute of Electrical and Electronics Engineers.

ACM – Association for Computing Machinery.

The following definitions are important when considering ethical behaviour:

» Legal covers the law, whether or not an action is punishable by law.

» Morality concerns questions of right and wrong, and is more often thought

of in relation to personal or individual choices.

» Ethics also concerns questions of right and wrong, but is more often used in

a professional context.

» Culture refers to the attitudes, values and practices shared by a society or

group of people.

Anything which breaks the law is termed illegal. Examples include copying

software and then selling it without the permission of the copyright holders

(see Section 7.2).

Morality is the human desire to distinguish between right and wrong. This varies

from person to person, and between cultures (something that is considered

immoral in one culture, may be acceptable practice in another, for example).

Immoral does not mean something is illegal (and vice versa). Creating a fake

news website, for example, is not illegal, but it may be considered immoral if it

causes distress to others. If the creator tried to obtain personal and financial

data, then it would be become an illegal act.

Similarly, hacking is generally regarded as immoral, but not illegal. However, it

becomes illegal if it compromises national security, or results in financial gain,

or reveals personal information, for example.

In short, there is a fine line between an immoral act and an illegal act.

Unethical behaviour is the breaking of a code of conduct. For example, if

somebody works for a software company and passes on some ideas to a rival

company, this would be regarded as unethical behaviour. If the software is

related to national security or is formally copyrighted, then it is also illegal.

It is essential to be clear whether any law has been broken.

The importance of culture is less tangible. When writing computer games, for

example, programmers need to be careful that they do not include items which

some cultures would find offensive or obscene. Again, this may not be unethical or

illegal, but could still cause distress. It is important to realise that boundaries can

easily be crossed; in some countries making fun of religion, for example, is illegal.

7 Ethics and ownErship

7.1.1 Computer ethics

Computer ethics is a set of principles set out to regulate the use of computers.

Three factors are considered:

» Intellectual property rights, for example, copying of software without the

permission of the owner.

» Privacy issues, for example, hacking or any illegal access to another person’s

personal data.

» Effect of computers on society, for example, job losses, social impacts, and

so on.

Internet use has led to an increase in plagiarism – this is when a person takes

another person’s idea or work and claims it was their own. While it is fine to

quote another person’s idea, it is essential that some acknowledgement is made

so that the originator of the idea or work is known to others. This can be done

by a series of references at the end of a document or footnotes on each page

where a reference needs to be made. Software exists that can scan text and

then look for examples of plagiarism by searching web pages on the internet.

7.1.2 Professional ethical bodies

There are a number of professional bodies representing individuals working in

the fields of computing and information technology that have developed their

own codes of conduct, to which members are expected to adhere. Belonging to

one of these organisations demonstrates your professional integrity by showing

that you are committed to upholding the standards they prescribe.

The British Computer Society (BCS)

The British Computer Society (BCS) is a professional body set up in the

UK, initially to represent the rights and ethical practices of all professionals

working in the IT and computing industries. It is now an international body

which works in close partnership with other groups to monitor and advise IT

practices across the globe.

The BCS Code of Conduct (www.bcs.org/category/6030) covers four main

areas:

1 The Public Interest

2 Professional Competence and Integrity

3 Duty to Relevant Authority

4 Duty to the Profession

The Institute of Electrical and Electronics Engineers (IEEE)

The Institute of Electrical and Electronics Engineers (IEEE) was set up in the

USA with the aims of

» raising awareness of ethical issues

» promoting ethical behaviour among professionals working in the electronics

industry

» ensuring engineers and scientists respect the need for ethical behaviour.

457591_07_CI_AS & A_Level_CS_178-195.indd 180 25/04/19 9:52 AM

181

7.1 Legal, moral, ethical and cultural implications

To help in this aim, the IEEE has also set out a code of ethics:

IEEE Code of Ethics

We, the members of the IEEE, in recognition of the importance of our technologies in affecting the quality of life

throughout the world, and in accepting a personal obligation to our profession, its members, and the communities we

serve, do hereby commit ourselves to the highest ethical and professional conduct and agree:

1 to hold paramount the safety, health, and welfare of the public, to strive to comply with ethical design and sustainable

development practices, and to disclose promptly factors that might endanger the public or the environment;

2 to avoid real or perceived conflicts of interest whenever possible, and to disclose them to affected parties when

they do exist;

3 to be honest and realistic in stating claims or estimates based on available data;

4 to reject bribery in all its forms;

5 to improve the understanding by individuals and society of the capabilities and societal implications of conventional

and emerging technologies, including intelligent systems;

6 to maintain and improve our technical competence and to undertake technological tasks for others only if qualified

by training or experience, or after full disclosure of pertinent limitations;

7 to seek, accept, and offer honest criticism of technical work, to acknowledge and correct errors, and to credit

properly the contributions of others;

8 to treat fairly all persons and to not engage in acts of discrimination based on race, religion, gender, disability,

age, national origin, sexual orientation, gender identity, or gender expression;

9 to avoid injuring others, their property, reputation, or employment by false or malicious action;

10 to assist colleagues and co-workers in their professional development and to support them in following this code of

ethics.

Jointly with the Association for Computing Machinery (ACM), the IEEE

has also developed a set of eight principles which govern the code of ethics

specifically among software engineers. The principles set out to ensure all

engineers meet an acceptable and consistent code of ethics. There are certain

expectations of the scientists and engineers from the general public as well

as from their peers. The actual eight principles behind the code of ethics and

professional practice were published way back in 1999.

An abridged version is shown below; a full version can be found at:

www.computer.org/web/education/code-of-ethics

Software Engineering Code of Ethics

1 PUBLIC – Software engineers shall act consistently with the public interest (contains 8 sub-clauses).

2 CLIENT AND EMPLOYER – Software engineers shall act in a manner that is in the best interests of their client and

employer consistent with the public interest (contains 9 sub-clauses).

3 PRODUCT – Software engineers shall ensure that their products and related modifications meet the highest

professional standards possible (contains 15 sub-clauses).

4 JUDGEMENT – Software engineers shall maintain integrity and independence in their professional judgement

(contains 6 sub-clauses).

5 MANAGEMENT – Software engineering managers and leaders shall subscribe to and promote an ethical approach to

the management of software development and maintenance (contains 12 sub-clauses).

6 PROFESSION – Software engineers shall advance the integrity and reputation of the profession consistent with the

public interest (contains 13 sub-clauses).

7 COLLEAGUES – Software engineers shall be fair to and supportive of their colleagues (contains 8 sub-clauses).

8 SELF – Software engineers shall participate in life-long learning regarding the practice of their profession and shall

promote an ethical approach to the practice of the profession (contains 9 sub-clauses).

7 Ethics and ownErship

There are 80 clauses and sub-clauses in total. We shall consider one scenario

and see how it fits into a selection of the clauses.

Mikhail works during the day for a software company called EthicalGamz developing

new software in a number of applications. Mikhail is part of a large team of software

engineers writing and testing new code. The team also do market research to help in

their development of new software for the future. Much of the work is commercially

sensitive and multiple layers of access exist to protect the company from unauthorised

sharing of data.

In the evenings and at the weekend, Mikhail works for his own company, MikhailSoft,

which produces software available to buy on the internet only. To save costs, Mikhail

uses coding he helped develop for EthicalGamz in his own software. He also outsources

some of the work to software engineers in other countries where the wages are much

lower and ethics policies are more lax. This saves him a lot of time and money when

producing his own software. Mikhail does not pay any licensing fees to EthicalGamz and

makes no reference to any code used from that company in his own products.

We will now consider the ethical implications of the above scenario using the

following sub-clauses from the Software Engineering Code of Ethics.

1.03 approve software only if they have a well-founded belief that it is safe, meets

the specification and passes the appropriate tests and does not diminish the

quality of life, diminish privacy or harm the environment;

There is an ethical issue here since the software written by personnel from

other countries may not meet the specification requirements or appropriate

tests. It could lead to any of the three factors being violated, for example,

the software may contain spyware of which Mikhail is unaware.

2.02 not knowingly use software that is obtained or retained either illegally or

unethically;

Mikhail has no control over the coding being developed by his overseas team,

furthermore, using the coding from EthicalGamz is illegal use.

3.05 ensure an appropriate method is used for any project on which they work or

propose to work;

Using external companies (in his own country or overseas) may be used at

various steps in the production of Mikhail’s own software. Unless he applies

good managerial control, he will be unable to ensure methods used in projects

are appropriate or fully ethical in their implementation.

4.02 only endorse documents either prepared under their supervision or within their

areas of competence and with which they are in agreement;

Documentation produced by third party developers is not produced under

Mikhail’s direct supervision, indeed some of the work done overseas may be

outside Mikhail’s sphere of knowledge which probably removes his ability to

objectively endorse the external work being done.

5.03 ensure that software engineers know the employer’s policies and procedures

for protecting passwords, files and information that is confidential to the

employer or to others;

457591_07_CI_AS & A_Level_CS_178-195.indd 182 25/04/19 9:52 AM

183

7.1 Legal, moral, ethical and cultural implications

By using software developed by EthicalGamz for his own use, Mikhail may need

to give passwords and access to other files to engineers working for his own

company, MikhailSoft. This would allow non-authorised personnel access to files

and information stored on Ethical Gamz computer systems leading to a potential

security breach.

6.05 not protect their own interest at the expense of the profession, client or

employer;

By using coding from EthicalGamz, Mikhail is enhancing his own interests at the

expense of the company and his colleagues at that company.

7.03 credit fully the work of others and refrain from taking undue credit;

By using coding from EthicalGamz illegally and unethically, and by making no

reference to the source of his ‘illegal’ code, Mikhail is effectively taking full

credit for all the work done by his colleagues.

8.07 do not give unfair treatment to anyone because of any irrelevant prejudices

Mikhail may dismiss overseas workers who do not agree with his own political

or religious beliefs and such dismissals would be deemed unfair and break this

code of practice.

EXTENSION ACTIVITY 7A

Using the example above, consider the following eight sub-clauses and

decide how (or if) Mikhail is breaking the code of ethics in each case.

1.01 accept full responsibility for their own work

2.03 use the property of a client or employer only in ways properly authorised,

and with the client’s or employer’s knowledge and consent

3.03 identify, define and address ethical, economic, cultural, legal and

environmental issues related to work projects

4.04 not engage in deceptive financial practices such as bribery, double billing

or other improper financial practices

5.02 ensure that software engineers are informed of standards before being

held to them

6.08 take responsibility for detecting, correcting, and reporting errors in

software and associated documents on which they work

7.02 assist colleagues in their professional development

8.09 recognise that personal violations of this Code are inconsistent with being

a professional software engineer

7.1.3 Impact on the public

Figure 7.1 summarises the potential impact of any software or hardware being

developed on the general public.

▲ Figure 7.1 Potential impact of software or hardware being developed on

the general public

While software engineers and scientists consider the Software Engineering Code

of Ethics, the impact on the general public cannot be ignored.

This section begins by considering three instances in which computer hardware

or software led to expensive errors, which impacted on the general public.

LA airport shutdown in 2007

In this example, aeroplanes at LA airport (in the USA) were grounded due to a simple software issue: a faulty network

card in a device continued to send incorrect data over the airport’s network. Eventually, the whole of the USA Customs

and Borders Agency came to an abrupt standstill at LA airport. This resulted in all flights leaving and landing at the

airport being cancelled for about eight hours until the fault was cleared. It cost several million US dollars in lost

revenue to the aeroplane operators. The impact on the general public was cancellation of holidays, loss of business

and general frustration.

Exploding laptop computers in 2008

Japan holds an annual trade show displaying the latest in computer technology. In 2008, during the trade show, a

number of Dell laptop computers burst into flames under the full view of the visiting public and television cameras.

The problem was traced back to faulty batteries in the laptops which had been overheating and eventually exploded

and burst into flames. As if this was not enough, the problem escalated when Apple reported similar problems with

some of its tablets, laptops and desktop computers. Some 100 million computer devices had to be recalled at an

estimated cost of over 300 million US dollars to the manufacturers. The impact on the general public would have been

devastating if this problem had not been discovered before the devices were generally available to buy.

Airbus A380 incompatible software issue in 2006

In Europe, Airbus Industries uses a number of factories throughout Europe where the design, development and

construction of aeroplanes takes place. During 2006, while the new A380 was being developed, a surprising issue

came to life: the software in two factories would not ‘talk to each other’. The factory in Hamburg (Germany) was

using an old version of CATIA design software while another plant in Toulouse (France) was using the latest version of

CATIA software. When a part of the A380 from Hamburg and a part of the A380 from Toulouse were brought together

for assembly, the wiring in the two parts did not match up (the cables could not be linked together). This was all

due to the fact that the two versions of the software produced different design specifications for the wiring. It cost

the company millions of Euros to redo the design and remanufacturing of parts where old software was still in use.

Fortunately, this was not a safety issue, but if some other design incompatibility had occurred after assembly of an

A380, the effect could have been catastrophic leading to possible loss of life.

457591_07_CI_AS & A_Level_CS_178-195.indd 184 25/04/19 9:52 AM

185

7.1 Legal, moral, ethical and cultural implications

All of these examples are cost-related, but still had – or potentially had – an

impact on the general public. Regrettably, there are many other examples.

Other issues which can affect the general public and businesses include

» companies selling software systems which do not meet the required standard

for security (inadequate protection against hacking, spyware and other

security issues)

» the covering up of security issues (such as the XEN security threat which

forced several cloud servers to become compromised – an attempt was made

to cover up the issue but the affected cloud operators had to come clean)

» the release of private data (such as the celebrity photo leaks, when a cloud

server was hacked)

» social media not policing subversive activity, such as hate mail and cyber

bullying. Such activity is undergoing close scrutiny by several countries

around the world

» search engines giving results at the top of the search due to donations to

the search engine operators.

EXTENSION ACTIVITY 7B

Bearing in mind some of the issues raised above, consider these two

questions.

1 Should we police the internet to stop certain activities taking place?

2 Should governments have the power to close down websites (such as

Twitter or Facebook) which do not remove hate mail, incitements to

violence or unacceptable photographs from their sites?

ACTIVITY 7A

1 Describe why it is necessary to produce a code of ethics to cover the

computing and electronics industries.

2 Mariam and Asma were having a discussion about whether or not the

internet should be policed.

Mariam was in favour of the argument and put forward two reasons.

① It would prevent illegal material being posted on websites, such as

racist comments, pornography, terrorist activities and so on.

② Some form of control would prevent children and other vulnerable

groups being subjected to undesirable websites.

Asma was against the argument and put forward two of her own reasons.

① Material published on websites is already available from other

sources.

② Policing would go against freedom of information and freedom of

speech.

Put forward your own arguments and discuss whether you think Mariam’s

or Asma’s reasons are valid.

3 Describe the main differences between the terms: legal, morality, ethics

and culture.

Give examples of each.

7 Ethics and ownErship

7.2 Copyright issues

Key terms

Piracy – the practice of using or making illegal copies

of, for example, software.

Product key – security method used in software to

protect against illegal copies or use.

Digital rights management (DRM) – used to control the

access to copyrighted material.

Free Software Foundation – organisation promoting the

free distribution of software, giving users the freedom

to run, copy, change or adapt the coding as needed.

Open Source Initiative – organisation offering the same

freedoms as the Free Software Foundation, but with

more of a focus on the practical consequences of the

four shared rules, such as more collaborative software

development.

Freeware – software that can be downloaded free of

charge; however, it is covered by the usual copyright

laws and cannot be modified; nor can the code be used

for another purpose.

Shareware – software that is free of charge initially

(free trial period). The full version of the software can

only be downloaded once the full fee for the software

has been paid.

7.2.1 Software copyright and privacy

Software is protected by copyright laws in much the same way as music CDs,

videos and articles from magazines and books are protected.

When software is purchased, there are certain rules that must be obeyed:

» It is illegal to make a software copy and sell it or give it away.

» Software cannot be used on a network or used on multiple computers

without a multi-use licence.

» It is illegal to use coding from copyrighted software in your own software–

and then pass this software on or sell it as your own – without the

permission of the copyright holder.

» It is illegal to rent out a software package without permission to do so.

» It is illegal to use the name of copyrighted software on other software

without agreement to do so.

Software piracy (making illegal copies of software) is a major issue among

software companies. They take many steps to stop the illegal copying of

software and to stop illegal copies being used once they have been sold:

» When software is being installed, the user will be asked to key in a unique

reference number or product key (a string of letters and numbers) which

was supplied with the original copy of the software (for example: 4a3c 0efa

65ab a81e).

» The user will be asked to click a button or box which states they agree to

the licence agreement before the software continues to install.

» The original software packaging often comes with a sticker informing the

purchaser that it is illegal to make copies of the software; the label is often

in the form of a hologram indicating that this is a genuine copy.

» Some software will only run if the CD-ROM, DVD-ROM or memory stick is actually

in the drive; this stops illegal multiple use and network use of the software.

» Some software will only run if a dongle is plugged into one of the USB ports.

(See also Section 7.2.2 regarding further copyright protection using DRM.)

The Federation Against Software Theft (FAST) was set up in the UK to protect

the software industry against piracy. FAST prosecutes organisations and

individuals involved in any copyright infringements.

457591_07_CI_AS & A_Level_CS_178-195.indd 186 25/04/19 9:52 AM

187

7.2 Copyright issues

Similar organisations exist in other countries. The following extract from a

newspaper article describes a typical example of how strict the anti-piracy laws

are in some countries.

TRADERS FINED $100 000

Two eBay traders from the United States of America agreed this week to pay a total of

$100 000 in damages after they were caught selling illegal copies of Norton security software.

The SIIA settled the case against the two traders who also agreed to stop selling illegal

software and provided SIIA with records identifying their customers and suppliers.

7.2.2 The internet and the World Wide Web (WWW)

Digital rights management (DRM) was originally set up to control what devices

a CD could play on. Preventing a CD from playing on a computer, for example,

would help stop it being copied illegally. DRM has since been updated to cover

more areas; it does this by using protection software to help stop the copying

of, for example, music tracks, video files or ebooks. DRM creates restrictions that

control what the users can do with the data. For example, allowing a music file

to be streamed over the internet but not copied, allowing an ebook to be read on

a tablet only, or a game requiring an internet connection to a certain website to

work, and so on. The aim of DRM is to ensure that any attempt made to break the

When you buy a product protected by DRM, it may come with a key which

licences a single user on one device and this key must be registered. Another

example – of which there are many – is Apple Music’s use of DRM layers in

streamed music to prevent a user downloading all the music in the first month

of a subscription and then cancelling their subscription.

7.2.3 Software licensing

Commercial software

Commercial software is available to customers for a fee, providing a licence

for one genuine copy to be used on a single device, or a multi-use licence for

multiple users. Occasionally, software is offered free of charge if an earlier version

was bought by the user. This type of software is fully copyright-protected and

none of the code can be used without the prior consent of the copyright owner.

Free software and the Open Source Initiative

The Free Software Foundation and the Open Source Initiative are non-profit

organisations that promote the benefits of giving users the freedom to run,

copy, change and adapt software. Examples of software licensed in this way

include: F-spot (photographic manager), Scribus (DTP/word processor) and

LibreOffice (Office Suite). Users are allowed to follow the four freedoms:

» Run the software for any legal purpose they wish.

» Study the program source code and modify it where necessary to meet their

needs.

» Redistribute copies of the software to friends and family.

» Distribute code modified by the user to friends and family.

Users do not need to seek permission to do the above since the software is not

protected by copyright restrictions. However, there are still some rules that the

user must adhere to. Users cannot

» add source code from another piece of software unless this is also described

as free software or open source software

457591_07_CI_AS & A_Level_CS_178-195.indd 187 25/04/19 9:52 AM

188

7 Ethics and ownErship

» use the source code to produce software which copies existing software

which is subject to copyright laws

» adapt the source code in such a way that it infringes copyright laws

protecting other software

» use the source code to produce software which is deemed offensive by third

parties.

While the two organisations promote the same four freedoms, they have

different basic philosophies.

Free Software Foundation focuses on what the recipient of the software is

permitted to do with the software.

Open Source Initiative focuses on the practical consequences offered by the

four freedoms; the aims are to provide effective collaboration on software

development by the users. There are ten principles that have been developed to

ensure the philosophy of the Open Source Initiative is adhered to:

1 Free Redistribution The license shall not restrict any party from selling

or giving away the software as a component of an aggregate software

distribution containing programs from several different sources. The license

shall not require a royalty or other fee for such sale.

2 Source Code The program must include source code and must allow

distribution in source code as well as compiled form. Where some form of a

product is not distributed with source code there must be a well-publicised

means of obtaining the source code for no more than a reasonable reproduction

cost, preferably downloading via the internet without charge. The source code

must be the preferred form in which a programmer would modify the program.

Deliberately obfuscated source code is not allowed. Intermediate forms such as

the output of a preprocessor or translator are not allowed.

3 Derived Works The license must allow modifications and derived works, and

must allow them to be distributed under the same terms as the license of

the original software.

4 Integrity of The Author’s Source Code The license may restrict source-

code from being distributed in modified form only if the license allows the

distribution of ‘patch files’ with the source code for the purpose of modifying

the program at build time. The license must explicitly permit distribution of

software built from modified source code. The license may require derived

works to carry a different name or version number from the original software.

5 No Discrimination Against Persons or Groups The license must not

discriminate against any person or group of persons.

6 No Discrimination Against Fields of Endeavor The license must not

restrict anyone from making use of the program in a specific field of

endeavor. For example, it may not restrict the program from being used in a

business, or from being used for genetic research.

7 Distribution of License The rights attached to the program must apply to

all to whom the program is redistributed without the need for execution of

an additional license by those parties.

8 License Must Not Be Specific to a Product The rights attached to the

program must not depend on the program’s being part of a particular

software distribution. If the program is extracted from that distribution and

used or distributed within the terms of the program’s license, all parties to

whom the program is redistributed should have the same rights as those

that are granted in conjunction with the original software distribution.

9 License Must Not Restrict Other Software The license must not place

restrictions on other software that is distributed along with the licensed

457591_07_CI_AS & A_Level_CS_178-195.indd 188 25/04/19 9:52 AM

189

7.3 Artificial intelligence (AI)

software. For example, the license must not insist that all other programs

distributed on the same medium must be open-source software.

10 License Must Be Technology-Neutral No provision of the license may be

predicated on any individual technology or style of interface.

Freeware

Freeware is software a user can download from the internet free of charge.

Once it has been downloaded, there are no fees associated with using the

software (examples include: Adobe Reader, Skype and some media players).

Unlike free software, freeware is subject to copyright laws and users are often

requested to tick a box to say they understand and agree to the terms and

conditions governing the software. This means that a user is not allowed to

study or modify the source code in any way.

Shareware

Shareware allows users to try out some software free of charge for a trial period.

At the end of the trial period, the author of the software will request that

you pay a fee if you wish to continue using it. Once the fee is paid, a user is

registered with the originator of the software and free updates and help are then

provided. Often, the trial version of the software is missing some of the features

found in the full version, and these do not become available until the fee is paid.

This type of software is protected by copyright laws and users must not use the

source code in any of their own software without permission.

ACTIVITY 7B

1 a) What is meant by the term software piracy?

b) Describe three ways of protecting software against deliberate

attempts at making copies to sell or give away.

2 A software company offers a suite of shareware programs. It contains a

7.3 Artificial intelligence (AI)

Key term

Artificial intelligence (AI) – machine or application which carries out a task that

requires some degree of intelligence when carried out by a human counterpart.

7.3.1 What is AI?

Artificial intelligence (AI) is a machine or application which carries out a

task that requires some degree of intelligence when carried out by a human

being. These tasks could include

» the use of a language

» carrying out a mathematical calculation or function

» recognising a person’s face

» the ability to operate machinery, such as a car, an aeroplane or a train

» analysing data to predict the outcome of a future event, such as weather

forecasting.

AI duplicates human tasks requiring decision-making and problem-solving skills.

7.3.2 The impact of AI

People often associate AI with science fiction, fantasy and robots. Numerous

films and books fuel this association. The science fiction author, Isaac Asimov,

went so far as to produce his own three laws of robotics:

1 A robot may not injure a human through action or inaction.

2 A robot must obey orders given by humans without question.

3 A robot must protect itself unless it conflicts with the two laws above.

However, AI goes way beyond robotics. It covers an ever-increasing number of

areas, such as

» autonomous (driverless) vehicles

» artificial limb technology

» drones, used to carry out dangerous or unpleasant tasks such as bomb

disposal, welding, or entering nuclear disaster areas

» climate change predictions

» medical procedures, such as eye operations where extreme precision is

required.

7.3.3 The impacts of AI on society, the economy and the

environment

As a result of increasing automation over the next few decades, the human race

will need to consider the impacts that AI will have on society, the economy

and the environment. So should we all be worried? In this section, we will

consider a number of existing AI technologies, plus some predictions for the

future, to help stimulate discussions. As mentioned in Section 7.3.2, AI is not

just about robots, but covers many areas (this is explored further in Chapter 18,

which explores specific AI technologies in more depth).

We will look at some of the areas mentioned in Section 7.3.2 in more depth and

consider the implications of using AI (the descriptions that follow will mix up

benefits and drawbacks – in Activity 7C you will need to consider the overall

impact).

7.3 Artificial intelligence (AI)

New developments in AI are constantly being announced and you are advised

to keep up to date by checking out the many websites that keep an eye on

AI development.

Below are some of the developments and impacts that are currently expected to

be seen in the near future.

Research has predicted that, by 2030, some 600 million jobs will be lost

globally and as many as 400 million people will need to retrain or switch jobs –

all caused by the inevitable advances in AI. The most likely jobs to be lost

are those doing medium- and low-skilled work, but high-skilled jobs (such as

hospital technicians, architects, engineers) are also at risk. This could lead to

civil unrest with large numbers of young people out of work, with few or no

employment prospects, unless they have a sought-after skill.

History has shown, however, that previous technological advances all ended up

creating a net increase in jobs. As automation takes over, jobs on the factory

floor are lost, but production becomes much faster and more efficient, thus

requiring an increase in the number people doing tasks that the automation

process cannot yet do, such as quality control, test driving new vehicles and

so on. Technology creates new jobs which are generally more interesting

to humans than the manual jobs which are lost. However, history does not

always repeat itself, so we need to prepare ourselves for a large reduction in

employment and think about how to redistribute wealth so that the overall

impact of AI will be positive.

It is predicted that, eventually, 99% of all jobs could be eliminated since the

increase in the use of AI is exponential – competition between countries

and companies to expand their economies will continue to fuel this growth.

One question that might be legitimately asked is, ‘if 99% of jobs disappear,

who will build the robots and maintain them?’ To answer that question,

let us consider a present-day solution to the question. 3D printers are

actually now being designed and made by other 3D printers with no human

interaction – the whole process is automatic with AI algorithms in control of

the building, design and maintenance of these printers. So, it seems logical

that other robots/machines will build and maintain future robots and other

AI systems.

An increase in AI will leave people with more time to pursue their hobbies

and have a better lifestyle. Previous industrial revolutions have led to steep

changes in the economies of countries that embrace the new technology.

Being left behind is not an economic option but is it a good environmental

option?

Improvements in AI technology can have a positive impact on the

environment. Scientists now have more information than ever about

what affects the environment. AI can help by finding patterns and

interconnections within the thousands of data sets. This helps scientists

make informed predictions about the environment and potential climate

change. Since this analysis is very complex, the use of AI systems can speed

up this process incredibly and allow the human race to take action much

faster than they could by present methods. Here are some potential ways in

which AI can help:

» AI can help us to conserve natural resources (for example, improve the

conservation of water supplies).

7 Ethics and ownErship

» Detection of pollution in the air and in the seas using AI is much more

accurate, allowing scientists to pinpoint the source(s) of pollution more

accurately and much faster.

» In the future it could be possible to combine weather forecasting and AI

to allow for better predictions about renewable energy resources needed

for the next few days. This would lead to a more precise automated

renewable energy forecast using solar, tide, thermal and wind energy

generation.

» AI would allow us to learn from nature’s ecosystems by monitoring and

modelling, for example, a river’s ecosystem. This would enable us to gain a

better understanding of what can affect the delicate balance of life in the

river. Such real-time environmental monitoring would allow us to quickly

take remedial action before the affects became irreversible. AI would make

this possible due to the ability to analyse vast amounts of very complex

(inter-related) data.

We will now look at three particular areas where AI could have a large

impact.

Transport

Some taxi companies are already looking at the introduction of autonomous

(driverless) cars. A customer can call up the taxi using an app on their mobile

phone, which also automatically handles the payment. Information about the

taxi (such as its location and estimated arrival time) would be sent to the mobile

phone until the driverless taxi arrives at the exact pick-up point. There would not

be any people anywhere in the chain, with AI systems taking total control. Some

car manufacturers are on the brink of actually supplying autonomous vehicles

(cars, buses and trucks). This would be much more efficient but would put many

drivers out of a job.

Criminal justice system

Advances in facial recognition systems is making fingerprinting in forensic

science almost obsolete. AI is also being used to automate legal work and some

courts in the USA have trialled the use of AI to sentence criminals and even

decide if a prisoner is eligible for parole. Is this a bad thing? Here are some

questions to think about:

» Does government use of AI need a warrant to allow online data to be

searched for all potential criminal activity?

» Can AI be used to listen in to our mobile phone conversations and assess our

emails? Social media companies are already coming under pressure in this

area – would AI help this or could criminals make use of it to hide criminal

activity?

» What about legal malpractice – what would be the mechanism to challenge

an AI inspired legal decision?

» How do we ensure no bias creeps into AI decision making processes? The

software being trialled in the USA to determine a prisoner’s suitability for

parole is already showing bias against black African Americans. How do

we ensure such prejudices by governments and individuals when using AI

systems is not allowed to occur?

7.3 Artificial intelligence (AI)

Advertising and use of data

You may remember the Cambridge Analytica scandal in 2018 which hinged

around potential misuse of data obtained from a social media company (nearly

90 million profiles had been used by the company leading some people to

believe it had influenced the 2016 USA presidential elections). AI could reduce

such occurrences by allowing much closer monitoring. It would need to be very

sophisticated and act quickly to have any real impact – human beings certainly

could not respond fast enough.

Algorithms can now tailor advertising aimed at specific people by using AI

machine learning – this is done by building personality profiles of every

internet and mobile phone user. Data is picked up from search engines, social

media and visits to websites – all this data can be analysed by machine

learning algorithms (see Chapter 18 for more details).

ACTIVITY 7C

Look through this chapter on the impacts of AI and produce a short essay or

wall display highlighting the pros and cons. Draw a reasoned conclusion and

debate the overall impact of AI with your classmates.

ACTIVITY 7D

1 In 2017, Diane Bryant, the chief operating officer of Google Cloud, claimed

that AI can:

n help us manage the Earth’s very scarce resources

n improve cancer diagnosis using precision medicine leading to

customised treatments

n lead to improvements in human rights in many countries due to cloud

computing, better connectivity and reduced costs in developing faster

computers.

Describe, with examples, why Ms Bryant’s claims could help people in the

future.

2 Give three different examples of AI.

For each of your examples, give one benefit and one drawback to the

general public.

1 Nicolae has joined a software company as a new team manager. During his
