Roko, you should be careful about saying that a materialist universe is better than a caring universe. If this is true, then a caring universe would make itself look like a materialist universe, just in order to be better, since a caring universe would want to do the better thing. So a claim like this would remove all your reasons for believing in a materialist universe, since a caring universe would become indistinguishable from a materialist one.
For similar reasons, it is obvious that Eliezer thinks a caring universe would be better: this is illustrated, for example, in his disagreement with the universe about whether stupidity should be punished with the death penalty.
