Not particularly, no. I care about communicating with my actual friends and family, not shadows of them.
I believe I'd still prefer this scenario over our current world, assuming those two - or destroying the world - are the only options. That's not very likely, though.
I would very much prefer CelestAIs utopia over this one, aliens and all.
I'd take status quo over this, and would only accept this with extremely low odds of intelligent life existing elsewhere or elsewhen in universe and the alternative being destruction.
I offer this particular scenario because it seems conceivable that with no possible competition between people, it would be possible to avoid doing interpersonal utility comparison, which could make Mostly Friendly AI (MFAI) easier. I don't think this is likely or even worthy of serious consideration, but it might make some of the discussion questions easier to swallow.
1. Value is fragile. But is Eliezer right in thinking that if we get just one piece wrong the whole endeavor is worthless? (Edit: Thanks to Lukeprog for pointing out that this question completely misrepresents EY's position. Error deliberately preserved for educational purposes.)
2. Is the above scenario better or worse than the destruction of all earth-originating intelligence? (This is the same as question 1.)
3. Are there other values (besides affecting-the-real-world) that you would be willing to trade off?
4. Are there other values that, if we traded them off, might make MFAI much easier?
5. If the answers to 3 and 4 overlap, how do we decide which direction to pursue?
