I’ve always felt that normative historical forms of transhumanism were deeply enmeshed in problematic anti-human & anti-democratic/anti-liberatory perspectives and it was only various radical and feminist cyberhumanisms that reclaimed it into something worth wanting (and which I agree are the point)
I think a big problem in the bio/technological advances scene, along with Science Fiction, that a lot of people get caught up in just a base power fantasy, and not something more imaginative and wholesome
Speaking as one of the trans people they try and speak for, I don't see that at all.
I am aggressively unfriendly toward attempts to rehabilitate that thinking under any rubric; you're just giving a way for the former issues to creep in.
