Yes, supposing they create humans in large enough numbers and that the
humans they create have experiences that are indistinguishable from ours.

Yes, but there are very strong reasons for thinking that the vast majority
would be created the "energy option". It's trillions of trillions of times
cheaper. (And as Robin points out, it doesn't require building a large
screen around our solar system.) I should say something about this in the
next version though.
When I said there might be ethical prohibitions to running simulations of
human lives, what I had in mind was the fact that human life contains so
much misery. I don't think there is anything immoral about creating
simulations per se.
