> If you believe the bitter lesson, all the handwavy "engineering" is better done with more data

Id say better model architechture than more data. A human can learn to do things more complex than an LLM with less data. I think modelling the world as a static system to be representation learned in an unsupervised fashion is blocked on the static assumption. The world is dynamical, that should be reflected in the base model

But yeah, definitely not an engineering problem. Thats like saying the reason a crow isnt as smart as a person is becauss they dont have the hands to type of keyboards. But its also not because they havent seen enough of the world like your saying. Its be ause their brain isnt complex enough
