Sure a lawyers office is probably able to to tackle more cases that a single lawyer. A big multinational with momentum probably a lot more power than a single human.
But say you put 5 Einsteins together, before he invented his theories. Do you think that his discovery process would go 5x faster? Does the team-einstein suddenly get 5x smarter?
I think not, the point here being that while corporations are super-human, they are not in the same league as true AGI. And that containment of corporations/governments is not a good place to learn about the containment of true AGI.
Maybe not, but it sure as hell be more than "1 Einstein unit" smarter. Whether that's 1.2 or 5 depends on various elements, but it surely would beat a single Einstein, if not by anything else, by mere ability to break down a problem to study in parts and assign it to each Einstein.
I mean, that's the reason we have research teams with multiple researchers on the same team.
That's at best a peripheral detail to the parallel the parent tries to draw.
Real AI might as well behave in any odd way -- the real point is that something like "more powerful than human intelligence" already exists, in the form of these aggregate entities.
