You are correct. But it's not 100% certain whether we would be capable of setting up a world simulation that would create intelligent agents of the human level.

You are correct. But it's not 100% certain whether we would be capable of setting up a world simulation that would create intelligent agents of the human level. And much less certain, (1) are we able to set up such simulation in the next couple of centuries, and (2) will the simulation produce these intelligent agents after having been running for only a couple of centuries (wall clock time). Btw, Crystal Nights by Greg Egan is a fascinating short story: http://ttapress.com/553/crystal-nights-by-greg-egan/ http://ttapress.com/553/crystal-nights-by-greg-egan/
