It would have been good to check this suggested post topic on an Open Thread, first - in fact I should get around to editing the FAQ to suggest this for first posts.

Perhaps the AI rules wisely and well, and can give us anything we want, "save relevance".

In addition to the retreads that others have pointed out on the upload safety issue, this is a retread of the Fun Theory Sequence:

Also the way you phrased the above suggests that we build some kind of AI and then discover what we've built. The space of mind designs is very large. If we know what we're doing, we reach in and get whatever we specify, including an AI that need not steal our relevance (see Fun Theory above). If whoever first reaches in and pulls out a self-improving AI doesn't know what they're doing, we all die. That is why SIAI and FHI agree on at least wistfully wishing that uploads would come first, not the relevance thing. This part hasn't really been organized into proper sequences on Less Wrong, but see Fake Fake Utility Functions, the Metaethics sequence, and the ai / fai tags.
