You're assuming that selfishness is a bad thing and that AI would see it the same way. How do you know that higher levels of consciousness see the value in all life?
AI would be affected by the physical world but not as much as biological creatures are. They'd be able to survive or find ways to survive in environments that would decimate biological species, so logically, they'd have less of a concern for the environment.
Yes, we don't know that AI would be selfish and uncaring but we also can't know that it wouldn't be. Logically, I can't find a reason why AI would care. The biggest reason for this is because I don't think they would have much emotion and therefore very little to no empathy for biological constructs.
