What is “better in general”? I don’t particularly mind the human species going extinct, it’s unlikely there’ll be no life left over. No one knows the nature of the universe.

In any case, it’s incredibly unlikely we’ll go extinct anytime soon. Maybe climate change etc causes extreme loss of life, but humans are so adaptive, some will surely survive.

No one can even define “enlightenment” either. Maybe we already are, maybe such a thing doesn’t exist. Currently, it’s just a story element.

The good of the many outweighs the suffering of the few. Achieving perfect homogeneity is desired. Or something like that.
