Those are very strong claims, do you really believe an LLM can't be trained to solve Rubik's Cubes?
Can you imagine what if feels like to be a LLM?
Can one LLM have a better sensation of what it feels like to be a different LLM (say one that score a little better?)?
You design circularly defined criteria...
honestly I'm pretty sure opus could solve a rubiks cube if you just gave it the layout if the sides and looped until it would solve it
or even just take a picture of the thing, since they can digest visual input now
