The reputation of a university takes decades to shape and is tied to the reputations of individual professors. For the other schools to "learn to replicate" Berkeley's success, all of their professors would have to become the top experts in their fields overnight. If the professors knew how to do that, they would have done it already, and then a lot of them would have tried to move Berkeley because it has a better reputation.

I'm not saying the other schools have no experts, just that it's a situation where talent tends to concentrate.
