You assume that any AI worth the label will already be as capable as current PCs.
But perhaps there is a tradeoff? Maybe becoming "intelligent" in the way we understand it is incompatible with the "dumb calculator/encyclopedia" capabilities of regular computers? Maybe true AI will necessarily lose the ability to look anything up instantly or calculate large columns of numbers?
I don't really believe that, but it is a possibility.
I've sort of had the same idea. I've wondered wether the power required to have a robot process all it would need to in order to move around and interact with the world by responding to all the different stimuli (optical, audio, kinetic) wouldn't leave many CPU cycles left for doing the super human things we're used to computers doing.
