Did you see https://thegradient.pub/othello/ ? They fed a model moves from Othello game without it ever seeing a Othello board. It was able to predict legal moves with this info. But here's the thing - they changed its internal data structures where it stored what seemed like the Othello board, and it made its next move based on this modified board. That is, autocomplete models are developing internal representations of real world concepts. Or so it seems.
