Genuine understanding is the worlds most valuable commodity right now

There are monsters in your LLM. (Murray Shanahan)

$We need AIs with PHYSICAL experience (Jeff Beck) Jeff Beck spent years studying computational neuroscience with Alexandre Pouget, Peter Latham, and Wei Ji Ma before founding Noumenal Labs. In this conversation with Tim Scarfe, he argues that language models are fundamentally limited because they manipulate symbols without the physical grounding that gives those symbols meaning. Beck walks through the Bayesian brain hypothesis — the idea that our brains maintain probabilistic models of the world, built from direct sensory experience. Language, he says, is just a thin lossy summary of that richer internal model. He points to Markus Meisters work showing that human information output runs at roughly 10 bits per second, a tiny fraction of what comes in. The conversation gets interesting around the question of whether AI systems can genuinely understand anything. Becks position is clear: until a language model produces something genuinely novel — not recombined from training data — he wont call it intelligent. The second half turns to alignment — Beck argues that you cannot separate someones beliefs from their reward function just by observing their behavior, a claim with serious implications for AI safety.
