I think the best you'll get will be tied to mental powers we know we are capable of. Think of the autistic spectrum and the savant syndrome, like Rain Man you mentioned. In that case, he had deep memory (e.g. perfect recall/photographic memory) but he didn't have a broad enough capacity to know how to do anything with it. Some call certain cases of autism "severe intelligence" because it is quite powerful but not very amenable.

The problem, of course, is that these states are flawed. Will we have more people with the brain capacity closer to that of Einstein or Da Vinci? Perhaps. But what you are wondering--will we have more powerful mental capacities in general--could take generations before we would even see a difference. It would be an evolutionary development. Do we have, on average, a higher capacity for intelligence than we did 4,000 years ago? I don't know. It's an interesting question.

So...no autolevitation, but perhaps a much higher mental capacity to develop and use technology that's pretty damn close.
