The human purpose of education in an age of abundant intelligence

For most of history, human beings had to develop their own intellectual capabilities because there was no alternative. Artificial intelligence is breaking that connection.

Information is already effectively free. Increasingly, understanding is also available on demand. Modern AI systems can explain difficult concepts, analyse unfamiliar situations, compare hypotheses, criticise arguments, verify calculations, and patiently revisit a problem from multiple perspectives.

There is no need to deny this in order to defend education.

The case for education must rest on something deeper than economic necessity or human cognitive superiority.

We should study not because machines cannot think for us. We should study because thinking is part of what keeps us fully human.

From intellectual labour to cognitive fitness

Modern people rarely need physical strength to survive. Machines lift heavy objects. Vehicles carry us over long distances. Elevators take us upstairs. Industrial systems perform physical work that once occupied much of human life.

Yet we still exercise.

We lift weights that do not need to be moved. We run without travelling anywhere. We cycle on stationary machines and climb stairs that lead to no destination. From a narrow economic perspective, much of this activity is pointless.

But that is not why we train.

We exercise because the human body deteriorates when its capacities are never used. Strength, balance, endurance, and mobility are goods in themselves. They give us health, confidence, independence, and a greater ability to inhabit the world.

Physical training ceased to be primarily labour and became a practice of human maintenance. The same inversion is now taking place in education.

One no longer needs to study primarily to store information, just as one no longer needs to walk in order to travel. One studies as an athlete trains: not because every intellectual movement is economically necessary, but because the movement develops and preserves the person performing it.

These abilities may still produce economic value. But that is no longer their deepest justification. They are forms of cognitive fitness.

Critical thinking as defensive control

There is also a practical reason to preserve our intellectual strength. The more capable AI becomes, the more dangerous total cognitive dependence becomes.
