Why AI cannot take over human knowledge

AI will take over many tasks. But knowledge, meaning the understanding, judgement and responsibility people bring, is different.

We know more than we can tell

The philosopher Michael Polanyi called this tacit knowledge. A nurse senses a patient is deteriorating before the numbers change. Much of this knowledge has never been written down, so it isn't in the data AI learns from.

The world keeps changing

AI learns from the past. New laws, markets and crises need people who reason, test and update. Research has even found that models trained repeatedly on AI-generated content degrade, so fresh human knowledge remains essential to AI itself.

Someone must be accountable

Decisions in health, finance, employment and justice need a responsible person. AI can propose; people answer for the decision.

Trust, culture and purpose

Patients, clients and teams trust people. Local and cultural context is hard to capture fully in data. And AI has no goals of its own: people decide what matters.

The future belongs to people who combine human knowledge with confident use of AI.
