simple solution: sterilize EVERYONE, like with an extremely contagious airborne retrovirus or something, specifically engineered to be easily reversible with like one pill that is akshully extremely hard to manufacture (by which i mean it should be super hard to set up the factory, but the manufacture of the pill itself should be scalable af), just so that it'd be available only in the one distribution channel, which should be: the genehacking clinics that should be on every street corner in the world

Those clinics MUST be completely free of charge and ask no question: anyone whosoever who wants to opt-in to fertility gets a catalog of genetic edits with a box to sign (and an X or a fingerprint is a valid signature), checks the edits you want in the catalog and signs in the box. The first option is "civilization package": Von Neumann level smart + nearly Williams Syndrome cooperatebottery

EVERY option we will, by then, know how to edit should be in the catalog, including warrior gene and Down's Syndrome, just because freedom of choice AND who tf are YOU to choose what's good or not anyway (and the people stupid enough to want those are not going to go to the last pages of the catalog anyway, kekekekek)

women don't WANT to have five idiot kids by uncivilizable retards anyway, that only ever happens because they're too stupid to take the pill regularly

this satisfies hedonism AND maximal choice AND trivially inconveniences dysgenics, which is largely sufficient to prevent every social problem that already exists and could possibly get worse

> inb4 "but but we don't have that level of genetics knowledge yet": by the time we can engineer the retrovirus we WILL HAVE IT kekekeke

> inb4 "but but the genehacking clinics errywhere won't happen in countries that are shithole-poor malthusian hellscapes": yes, that's a problem solved.

> inb4 "but but if there are no unplanned kids then what about MUH PENSION": IF YOU'RE HERE THEN YOU'RE SMART ENOUGH TO PROGRAM INDUSTRIAL ROBOTS SO GET TO IT ALREADY YOU DUMB SHIT
