In 100 years, I could imagine a society where young people are expected to find a gender identity in the same way as they find other aspects of themselves, and maybe their gender identity changes a few times over their lives. Imagining such a society doesn't bother me at all. I think it's totally workable ...
Sure but it's a lot simpler to go in the other direction: Instead of 86/whatever genders, just one.
