Have you ever read anything on "String Theory"?? Scientists pine about how they wished reality would conform to the "String Theory", it is just mathematically beautiful and symmetric. But reality really refuses to conform to it, lol!
I have read that String Theory is just mathematically beautiful and a great effort, but it holds little reference to physical reality.
I hope something as fast as the quantum computer is possible though. That would really be neat. But so far, unless quantum mechanics can be rationally explained, I see no hope for it.
