If you were an upload, would you make copies of yourself?

Yes. I'd make as many copies as was optimal for maximising my own power. I would then endeavor to gain dominance over civilisation, probably by joining a coalition of some sort. This may include creating an FAI that could self improve more effectively than I and serve to further my ends. When a stable equilibrium was reached and it was safe to do so I would go back to following this:

Where's the fun in that? The only reason I could see doing it is if I wanted to amass knowledge or do a lot of tasks... and if I did that, I'd want the copies to get merged back into a single "me" so I would have the knowledge and experiences.

If right now is the final minutes of the game then early in a WBE era is the penalty shootouts. You don't mess around having fun till you and those that you care about are going to live to see tomorrow.
