A lot depends on the specifics of the scenario (for both AI and human-upload cases). I don’t know anyone who thinks that there’s anything important (for survival) that humans do which can’t theoretically be done by an electro-mechanical device.
So in theory, upload/AGI would be about as self-sustaining as biological entities (which is: rather fragile, and don’t have enough track record at scales that stress the ecosystem to know whether we are).
Presumably, the robots are a little more rational than humans in terms of how they maintain and replenish their resources, and how they ration themselves (aka: each other) to stay within bounds of current sustainability. So, even more unknown, but plausibly more sustainable than biological humans.
