An AI that is more intelligent than a human may be able to come up with plans for profit maximization that no humans can come up with.
A corporation is only going to be able to come up with a plan that a human _could_ come up with.
A corporation is merely a sociopathic human intelligence that is hell bent on profit-maximization.
Yet, a single corporation is intelligent enough to do this.
I think we already have achieved super-human intelligence.
Related to this, on the morality dimension, corporations can introduce a diffusion of responsibility [0] and enable a collection of humans to commit to profit-maximising acts that no single one of them would do. Less ominously, teams of cooperating researchers may do something similar on the innovation dimension: their combined efforts act as a 'super researcher' beyond the ability of any single human researcher.

If you're talking about AI with 'smarter than us the way we're smarter than chickens' as the standard I suppose I'd have to agree, but it seems like there's a big, very vaguely defined stretch between 'very smart human' and 'makes a very smart human look like an imbecile'
We make more and more things we don't need, in ever greater quantities, using more and more resources, and destroy the planet in the process. We won't stop until there's nothing left.
