Fuzzy Categories and Semantic Networks

A Princeton cognitive scientist says AI can't think like a child — and giving it more data won't fix that. If the field keeps scaling without solving what's actually missing, the gap between human and machine intelligence won't close. It'll just get more expensive. Tom Griffiths is a professor of psychology and computer science at Princeton, and one of the leading researchers working at the intersection of human cognition and AI. We cover: -why a child learns language from breadcrumbs while AI needs continents of data -the 250-year-old idea that quietly became the foundation of modern language models -what sycophantic AI actually does to your beliefs over time -why solving AGI might have less to do with scale and more to do with understanding what a child's mind really is. The hallucinations don't bother him — it's the sycophancy that should worry you.
