It doesn't matter what individuals believe. The rules exist to prevent people from doing dumb things that destabilize the market and when those rules are bypasses for belief reasons then the market will take that into account and discount the rules and the market loses its integrity. At that point you have signaled that the rules exist in order to facilitate corruption not oppose it, and you end up who knows where, but it certainly isn't better.
My predictions:
1) If the AI companies do end up running half the economy, we will have discussion for the rest of the human history about how the public got scammed by not being able buy in earlier at a lower price and how the late IPOs set in stone the oligarchy.
2) If the AI companies crash and burn, we will have discussion for several years about how everyone involved in running and financing them is a scoundrel who needs to go to jail for scamming us by selling us stock.
