I don’t think of selective gene editing of one person as eugenics and do think we will get that, we have some versions of it for born people already. Editing it out of humanity? No that’s probably a bad idea. One of my kids works in genetics and was horrified when I joked about her making designer babies like in Gattaca, so I don’t think science thinks it a good idea. Push on one thing, another pops up.

You might enjoy Octavia Butler’s Xenogenesis and Patternist books, if you like thinking about this stuff.
