A.I.s probably won't be the monolithic creations we've imagined them. It would be inefficient to localize them. There're so many processors all over the planet. Borrowing a little computational power from each is going to be what the A.I.s 'brain' is. Ya know when ya see a satellite camera of the Earth and you can clearly see the lights of cities? Yeah, that's essentially one giant neural network. We pretty much built the Earth a brain, and now it's starting to develop.
