Isn't there pretty much a consensus that committees and institutions are not all that smart?
I think you're confusing the categories of "intelligence" and power. Institutions are powerful. The smartest AI is still just a tool without the infrastructure to turn that into real world effects and someone to direct it.
It seems you have faith that this is inevitable and unavoidable. I get it, even rationalists succumb to religious thinking eventually. We're only human after all.
