Overview
Research at Columbia Engineering reveals that the brain's circuitry operates more efficiently than previously understood, challenging traditional views of how visual information is processed. Nuttida Rungratsameetaweemana proposes that the brain integrates thinking and seeing more directly than the conventional model suggests.

- Praise: Reverse engineering how algorithms in the brain work is a really promising path towards making genuine AI systems which would make the current crop of LLMs obsolete.
- Concern: Why are they using neural nets to model observed behavior when biological neurons work completely differently? This feels like a fundamental mismatch.
- Concern: The actual experiment is just training a large RNN to do a simple task — it seems hard to claim we've learned anything useful about brain function from this.
