If that happens catching up will be meaningless, everything we know and care about will change. You don’t have to be doomsday about it even, a self improving AI will quickly be more efficient than a human brain, all the data centers will be useless, tech companies will collapse (so will most others), everyone will have an incredible AI resource for the price of a hotdog. There’s no way it wouldn’t leak from whoever made it, either by people or by the AI itself.
