Hopefully anonymous: There are strong warnings against posting too much, but my personal suspicion is that the next generation of AI will not colonize other planets, convert stars, or any of the things we see as huge and important, but go in the opposite direction and become smaller and smaller. At least, should the thing decide that survival is ethical and desirable.

But as sand or worms or simply irrelevant, the result is the same. We shouldn't be worried that our children consume us: it's the nature of life, and that will continue even with the next super intelligent beings. To evolve, everything must die or be rendered insignificant, and there is no escape from death even for stagnant species. I think that will hold true for many generations.
