So then how do we define natural general intelligence? I'd argue it's when something can do better than chance at solving a task without prior training data particular to that task. Like if a person plays tetris for the first time, maybe they don't do very well but they probably do better than a random set of button inputs.

Likewise with AGI - say you feed an LLM text about the rules of tetris but no button presses/actual game data and then hook it up to play the game. Will it do significantly better than chance? My guess is no but it would be interesting to try.
