Kaj: No, more aren't born every minute, they are all simply there, and if one cannot tolerate vanishingly small frequencies or probabilities then there will always be things other than your brain spontaneously configuring themselves into "your brain resolved to abandon those you had resolved to help" for every real or hypothetical "someone" you might resolve to help. For what its worth though, if "you" is the classical computation approximated by your neurons then it isn't "you" in the personal continuity relevant sense that does any given highly improbable thing. The causal relations that cause unlikely behaviors exist only in the configuration space of the universe. They differ from the causal relations that exist in the abstract deterministic computation that you probably experience being.

Frank: See Kaj

Eliezer: What's up with continuous physics from an infinite set atheist?

Unknown: 2 seems plausible but it's definitely not an argument that most people would accept

Will Pearson: Shut up and multiply. 150K/day adds up to about 3B after 60 years, which is a conservatively high estimate for how long we need. Heads have a volume of a few liters, call it 3.33 for convenience, so that's 10M cubic meters. Cooling involves massive economies of scale, as only surfaces matter. All we are talking about is, assuming a hemispherical facility, 168 meters of radius and 267,200 square meters of surface area. Not a lot to insulate. One small power plant could easily power the maintenance of such a facility at liquid nitrogen temperatures.
