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.
