Most universes are hostile to life, and at most would develop something like prokaryotes.
I mean, by anthropic principle, we couldn’t ever be born in such universes. And I think this only applies if we consider various tunings of our known laws of physics. At the two extremes of the possibility spectrum though there is:
the constants aren’t really constants but emergent phenomena themselves, and thus this is actually the only universe possible
the laws aren’t in any way constant, the general symmetries and principles aren’t constant, there’s a whole Tegmark Type IV multiverse out there to explore
In the former case, then I guess there’s not much to complain about. In the latter, there surely are an infinity of universes better than this one (though also many much worse).
