Well honestly, isn't the definition of quantum computers the fact that it uses quantized states of something to account for a number of bytes, or rather a number? And the fact that this might allow logic gates with much higher clock frequencies, maybe even none at all compared to what's possible tod...
Well, the fact that the series http://i.imgur.com/yilwg.png converges to f(x) as http://i.imgur.com/nj6pU.png is essential, since it's an approximation that with infinite terms, IE infinite computer power is equal to the sought value is essential in the described problem. Yeah, I'm just namedropping...
I'm not saying that they will be replaced, but since most of them are generated by combining multiple poses, physical simulations and inverse kinematics, tweaking them is no big deal whatsoever. But on the other hand, having them look right takes time and iterating.
