For example what if there is a five billion dollar supercomputer data center that can simulate a single intelligence that is say in the top 10% of smartness of people and it outputs one word every five seconds.
In that example, even though it is superintelligent there would be a limit to how fast it can make more of its own data centers. And even if it can research its own development to make itself more efficient, there is probably some lower bound on the hardware required. Like no matter how smart the superintelligence is, it's probably not going to be reducing its own size to fit into everyones pre-existing phones. And even if it can do its own hardware research it would still have to be implemented, by some kinds of workers or robots. And those robots don't get made instantly.
Probably Eliezer Yudkowsky has a galaxy brain reason why this is wrong?
If it did, nobody here would have a job and we would be already deep into the "reorient society or fight the Machine" phase.
