At the limit sure there’s variance, but our shared selected history has a lot in common, something a non-human intelligence would not get for free: https://www.lesswrong.com/posts/4ARaTpNX62uaL86j6/the-hidden...
I’m also not a moral relativist, I don’t think all values are equivalent, but you don’t even need to go there - before that point a lot of what humans want is not controversial and the “obvious” cases are not so obvious or easy to classify.
Humanity doesn’t have unified interests or shared values on many things. We have different cultural memories and different boundaries. What to some is an expression of a fundamental right is an affront.
