This is all the vibe I get too, but also just: the science isn't there. You can actually end up worse off trying to do PGS screening for intelligence; we may not know enough to do it without also selecting for negative traits, like autism (intelligence and autism aren't as I understand it inextricably linked, but can be confounded in polygenic scores; the notion that you can get any reliably signal at all from PGS for intelligence is itself super shaky). There are embryo selection companies that did intelligence screening that stopped doing it, because it turned out their methodologies were busted.
