AI is already improving itself. Most / all of the coding harnesses are AI-written.
And yet… there are still people telling AI how to improve itself.
IMO there will always be a level of abstraction at which AI needs guidance. Perhaps ASI means it decides everything on its own, but I don’t think so. Genius humans often excel at the how but not the why, or even the what. So far there’s no indication that AI is different.
