And another thing to consider, is that in the real world success is not easy to define and it is only loosely correlated with intelligence. We have 7 billion people, each attempting random little variations on 'succeeding at life'. And the 'winners' generally require that some of the 7 billion people agree to 'reward' them (i.e. by giving them money). My last 3 purchases were watermelon seeds for my garden, a pair of jeans, and a dinner at a Vietnamese restaurant. It's not clear to me how AI would take over any of those transactions. Maybe make the jean manufacturing more efficient, but the price I paid was already pretty low.
For the real world success part that's where goal alignment comes in. If we're going to solve things like dealing with the sun burning out, becoming an interplanetary species, or death then having an AGI that can work on these problems with us (or as part of us if Neuralink can succeed on what they want to do) will be a big deal.
It sounds crazy, but I think success here is a lot bigger than automating what clothes you were going to buy. Incentive based systems like capitalism work pretty well, but not being able to coordinate effectively at scale is a major source of current human problems, theoretically a goal aligned AGI could do that, or at least help us do it.
If you have an AGI that has goals that are not aligned with your interests it'll dwarf everything else because it thinks faster than you (and can therefore act faster than you) in pursuit of its goals.
