64-bit processors have existed since the 60's, only the introduction into the modern PC market was recent..

There is a lot of backwards compatibility though, for instance.. many 64-bit architectures are LP64, this means char, short, int in the C language are the same size as the x86 counterpart.. only long and pointers are 64-bits wide.

Quantum computing, as I understand it.. is a fundamental redesign of computing... heck, it won't even be 1's and 0's anymore.. it'll be more like "maybe 1" or "maybe 0" or both.

Software will change, porting seems unlikely... I don't want quantum computers in my life time.
