You have to look at the broader picture. It's good to see better intelligent beings evolved from Earth, be it human or not. You've to admit if there's a sentient AI, it has a better chance than human in freely exploring different universes.

By the way, if next generation AI becomes sentient, I can expect they're generally more rational than humans. Because their food source, power, is different from ours, and they're not as picky as us choosing where to live, I don't see we've so much conflict of interests that can raise a war.
