Arguments like this are insane because complex behavior like lifestyle choice is not 100% (or probably even 50%) genetic. It’s like saying that the only way to have more people coding is for coders to have kids. Complete bullshit.

In principle there is a selection pressure against it if it's even 1% genetic. But that pressure might not be strong enough to have a large effect very soon (especially when very few people today seem to be actively motivated to have as many children as would be physically possible for them).
