For a lot of this stuff, I find it helps to separate the concept from the implementation: Imagine how different current debates over transgender stuff would be if it was an atomically-perfect and reversible transformation done by benevolent genie.

when I see futurists or transhumanists talk about a timeline where humans are uploaded or become cyborgs or whatever, and then they turn around and say stuff like “feminism is bad”, I am utterly baffled.

I think some of them really just want to live forever in a conventionally beautiful body with superpowers.

Sure, Chad Jockson III might temporarily transmit his mind at light speed to Alpha Centauri, but when he gets there he expects to re-inhabit a pretty-similar body.
