Aren't you anthropomorphizing AIs? If an AI's goals entail communicating with the rest of the world, the AI has the option to simply wait as long as it takes. Likewise, it's not obvious that an uploaded human would need or want to run at the fastest physically possible timescale all the time.

And if outward- and inward-looking civilizations ever need to compete for resources, it seems like the outward-looking ones would win.
