AI, Human Cognition and Knowledge Collapse – Daren Acemoglu
3•aanet•2h ago
From the abstract:
"We study how generative AI, and in particular agentic AI, shapes human learning incentives and the long-run evolution of society’s information ecosystem... Learning exhibits economies of scope: costly human effort jointly produces a private signal about their own context and a “thin” public signal that accumulates into the community’s stock of general knowledge, generating a learning externality.... The model highlights a sharp dynamic tension: while agentic AI can improve contemporaneous decision quality, it can also erode learning incentives that sustain long-run collective knowledge. "

When you struggle through a hard problem, you get two things: the answer, and a slightly sharper mind. AI gives you the first and skips the second.
That's fine once. Scaled across an entire generation of knowledge workers, over a decade that's the collapse Acemoglu is worried about.
We're not just outsourcing tasks. We're outsourcing the friction that makes people grow.
