ONLY THE BIOLOGICALLY FIT SHOULD PROCREATE.
I would agree with that, but this time it is not actually "natural" selection. This is man-made, as the articles discuss. If this trend continues, nobody would procreate, except the elites who are quite aware of those trends and what is causing them, and can protect themselves. So, it may end up being a very "unnatural" selection where only a small group of degenerate and sick elites procreate while the masses are forced out of the gene pool. Despite all the hype around transhumanism, it is actually a lie/scam and the elite are still dropping dead quite regularly. The eldest Rothschild in Europe recently died in his 90s. As such, procreation will remain an important goal and the elite will probably be the only group going forward being able to both beget children and afford raising them.
