There's a perspective where it makes sense to keep throwing money at it.
Even 'borrowing' from the future would be the right thing to do.
If the end result is AGI that changes everything, its analogous to inflating away debt. It would make everything so cheap and abundant that the initial cost doesn't matter, and getting there as fast as possible is the right thing to do.
That said, its not where my moneys going
AGI isn't going to be centralized for basically the same reasons that central planning cannot produce prosperity. It's a fools errand.
Btw I was thinking of the agi+singularity+transcends physics SciFi scenario
