Permutation City

Consider that downloading your consciousness into a computer was possible. That means you could live forever, as long as somebody maintained that computer. Now imagine that a rich guy employed a software developer to write a software package that was self-preserving and could not be destroyed because it was deployed across some vast system, and in that package were various levels of habitat for downloads to live. Forever is now becoming more of a possibility.

Welcome to Permutation City. What could possibly go wrong?
