Even though I am generally a supporter of eugenics actually doing this plausibly is ridiculously hard: Polygenic scores aren’t environmentally robust. Pleiotropy and epistasis mean that when you alter one (what you wrongly think is a) monogenic trait, you’re probably going to get effects elsewhere almost inevitably since our knowledge is very limited here.

We cannot actually do eugenics because of this and many other reasons. We need more tech and we need more insight. And we should work on that.
