Physicist Argues LLMs Are Limited by Language, Cannot Understand Reality

skdh · x · 2026-08-06

Recalling a dinner at the Royal Society with figures like Demis Hassabis and Tim Gowers, a physicist discusses AI's potential creativity in mathematics. Gowers viewed the evolution of proofs as a meta-extrapolation of methods, arguing that creativity doesn't come out of nowhere and human minds aren't unique in injecting random elements.

The author notes that new ideas are essentially about connecting dots, something a computer can theoretically reproduce. However, they remain skeptical about current LLMs. They argue that language is a lossy tool developed to transfer information between human brains. Therefore, models trained solely on language will struggle to reconstruct a genuine understanding of reality.
