The following is an edited extract from Professor John Lennox’s latest work, 2084: Artificial Intelligence, the future of humanity and the God question, published by Zondervan.

One of the public intellectual Yuval Harari’s contentions is that many people researching into Artificial Intelligence do not concern themselves with consciousness for the simple reason that their AI systems are allowing them to create intelligence (simulated) that is not conscious – and that is sufficient for their purposes.

It is easy to get some idea of what this means. Suppose I take a taxi journey from the train station to a meeting in Oxford. The taxi driver is conscious – otherwise the journey is rapidly going to run into serious trouble. But if I undertake the journey in an autonomous vehicle, the taxi driver is superfluous. All I need to achieve my goal is an AI system that “knows” the route and can guide the car along it, but there is no need for a conscious driver at any stage. Or suppose I need heart surgery. The last surgeon I experienced was a conscious human being; the next, should I need it, may well be a non-conscious robotic AI system.

Genesis tells us that when God created humans in his image, he linked intelligence and consciousness together in one being, for he is himself like that – a conscious intelligent being. However, God, who is Spirit, links consciousness and intelligence together in a non-material being. The fact that God is Spirit shows that neither consciousness nor intelligence necessarily depend on a material substrate – another reason to think that humans will never be able to make a conscious material machine.

Humans were assigned work

Genesis 2:15 informs us that God gave work, in a garden, as part of the human raison d’être before sin entered into the world. That is why people who try but do not succeed in finding work often feel deprived and unwanted. Yet, work, though very important, is not all of life as it was essentially thought to be in the Communist concept of a “worker state.”

However, what is happening now is that, as suggested above, by decoupling intelligence from consciousness, AI would seem to be pushing us in the opposite direction to a situation where work becomes a smaller and smaller part of human activity.

Even if American futurist Ray Kurzweil is overly optimistic in saying that most human tasks will be taken over by robots by 2030, we need to think about what even a partial AI/robot takeover would look like in light of the biblical view that work is part of our God-given significance as human beings.

In the twenty-first century we might witness the creation of a massive new unworking class: people devoid of any economic, political or even artistic value, who contribute nothing to the prosperity, power and glory of society. This ‘useless class’ will not be merely unemployed – it will be unemployable.

Digital assistants, robots, and the like can be regarded as slaves, and the world already experienced a slave economy where the very few were served by the many. That very few did little work, and when society collapsed, having forgotten how to work, they had no idea how to rebuild. Some suggest it was for that reason that the Roman Empire eventually collapsed.

The concept of a “useless class” is chilling and dehumanising. The New Testament advice for believers is: “If anyone is not willing to work, let him not eat” (2 Thessalonians 3:10). It does not, however, say, if anyone does not work, let him not eat. It is almost as if Paul envisaged the possibility of unemployment.

If certain AGI pundits are right, the prospect of future techno-unemployment is worse than grim. In chapter 5, we gave some idea of the projected time-scale of job erosion in the survey by the University of Oxford’s Future of Humanity Institute. It is obvious that there is an urgent need to create many new jobs, and if they are not to disappear too rapidly, they will have to be jobs that humans can do better than algorithms.

This will mean that many, if not most, people will have to keep learning throughout life, a prospect that many will find either daunting or simply impossible. The techno-optimists hope that even if such people cannot be employed, there will be enough financial surplus from the new technology that they will be fed, housed, and supported throughout life.

But who will be paying for the new technological services – certainly not people who have no work? Where will the financial surplus come from? Such techno-optimism seems extremely naive! The extreme techno-pessimist view is, as University of Oxford philosopher Nick Bostrom warns, that humans will not in fact reach the final stage of unemployability, as an ascendant AI may well simply exterminate them.

Once AI masters the art of horticulture, will there be a job for Adam?

Yet according to Scripture, work is an important ingredient in human flourishing. How can those of us who are convinced of that fact communicate and maintain it in the face of a technological invasion of the workplace? Is our stark choice really between learning to work with robots or being replaced by them? Once AI masters the art of horticulture, will there be a job for Adam?

The problem is huge, and it starts not with retraining those that have already been employed, but with the basic education of children. The World Economic Forum reports: The jobs of the future will require students to have strong cognitive skills in mathematics and literacy, as well as soft skills such as problem-solving and creative thinking, to enable them to adapt to a quickly changing environment.

However, millions of children are not gaining these skillsets, either because they never started school, they have dropped out of school, or their school does not offer a quality education.

It would appear that 617 million children and adolescents fall below an acceptable standard in reading and mathematics. The tragedy here is that this represents an immense waste of talent and leads to severely reduced potential to escape long-term poverty. It is a sobering thought that AI may leave millions of children far behind, totally unable to compete with the more privileged.
