So, yes, the ultimate battle is with entropy, but we have a long way to go before that's the actual limiting factor.
Why not have thousands of them? What are you?
Otherwise, make an ethical argument that covering every inch of the planet in people is a good idea.
Otherwise, explain how you'll get the proper sterilization procedures working to control population growth and get resource consumption down to sustainable levels.
> In 1944, 29 reindeer were introduced to the island by the United States Coast Guard to provide an emergency food source. The coast guard abandoned the island a few years later, leaving the reindeer. Subsequently, the reindeer population rose to about 6,000 by 1963[5] and then died off in the next two years to 42 animals.[6] A scientific study attributed the population crash to the limited food supply in interaction with climatic factors (the winter of 1963–64 was exceptionally severe in the region).[1] By the 1980s, the reindeer population had completely died out.[2] Environmentalists see this as an issue of overpopulation.

Well, I'll grant you one thing: not quite sure what it is you're computing, but assuming your plan works, that was a surprisingly short path to conserving the universe's resources until your computational substrate suffers proton decay.
I still have only hunches of what computation has to do with actual lives. Please, explain your Evil Plan out loud.
As they die, some will take solace in a religious belief that numbers in the machine represent everything they were and ever will be. Others will just die.
A digital tombstone to a dead race.
If it does, why assume brain-meat is better, as opposed to worse?
I bet many people here would not doubt the moral value of the emulation of a human (feelings and such are simulated to the point of being real), but would highly doubt that it would be, well, the "same" person as the original.
The one thing nobody ever specifies about these crazy schemes, which would otherwise be a great way for humanity to get the hell off of Earth and leave the natural ecosystem to itself in our absence, is who will be root, and how he's going to forcibly round up everyone who doesn't like your crazy futurist take-over-everyone's-minds scheme. Hell, what's going to stop him from rampaging across the real Earth and universe, destroying everything in sight, while everyone else fucks around having fun in VR?
I'm really wondering why this nasty, insane idea has been cropping up more frequently lately in geek circles.
And that's not even starting into the sheer ludicrousness of claiming people's consciousness is pure software when we know that all kinds of enzymes and hormones affect our personalities!
That's a bug to fix in implementation accuracy. I'd obviously prefer more accuracy, but if it comes down to a choice between less-than-perfect available implementation accuracy or dying of old age, I'll happily take a less accurate implementation, especially one that preserves enough information to fix that issue later.
The much more serious bug I am concerned about is the continuity flaw: a copy of me does not make the original me immortal. I'd like the original me to keep thinking forever. Many proposals exist for how to ensure that. The scary problem that needs careful evaluation before implementing any solution: if you do it wrong, the copy will never know the difference, but the original will die.
The route to unfriendly AI is revenue-positive right up until it kills us.
