But human intelligence is weird. It's not clear to me that increasing the speed of my brain would really accomplish much in my day-to-day life. A lot of the value that I add happens during these 'Eureka' moments, often triggered when I am working on a different problem, taking a break, or after a good nights sleep. Adding more processing speed may or may not make that process more scalable.
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.
Sure it happens in Eureka moments which for you are when you take a break that might be a few hours, but if you're running a billion times faster then a few hours turns into a billionth of that time. That's what I'm trying to get at as an example - even assuming the exact same architecture otherwise.
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.
