IIT has many problems. but "pseudoscience" is like dropping a nuclear bomb over a regional dispute. it's disproportionate, unsupported by good reasoning, and does vast collateral damage to the field far beyond IIT. as in vietnam: "we had to destroy the field in order to save it."

who saw LLMs coming? e.g. decades (or even 5+ years) ago, X said: when machine learning systems have enough compute and data to learn to predict text well, this will be a primary path to near-human-level AI.

one criticism of large language models: they only model (represent) text with no models of the world. i take it this is an empirical (and conceptual) issue: all LMs handle text, some may develop world models to do so. what's the best evidence that LLMs do/don't have world models?
