When you have that feeling of understanding, it is important to recognize that it is a feeling.
We hope it’s correlated with some kind of ability to reason, but at the end of the day, you can have the ability to reason about things without realising it, and you can feel that you understand something and be wrong.
It’s not clear to me why this feeling would be necessary for superhuman-level general performance. Nor is it clear to me that a feeling of understanding isn’t what being an excellent token predictor feels like from the inside.
If it walks and talks like an AGI, at some point, don’t we have to concede it may be an AGI?
In people, these are correlated, but one does not necessitate the other.
