> If America doesn't do it, China will, and in a generation will be swollen with a population so much more fit as to make the question of the US standing toe-to-toe laughable. If China doesn't, Russia will.

China already spent a generation letting people shoot themselves in the foot with specifying genetic preferences in children. Don’t know what I mean? I’m talking about the gender trait. This is something determined by genetics and something that genetic engineering can allow people to specify, albeit China’s previous method of discarding female newborns is a bit of a low tech way of accomplishing it,

The great thing is we have a clear example of the dangers of unchecked genetic manupulation. Mobs are stupid, and also tend to reduce diversity as everyone wants to pick the obvious good traits. They thought being male was a better trait, and giving people the power to choose the trait let them shoot themselves in the foot as a society. You end up with the massive gender imbalance and that’s the least worrisome of repercussions if we get rid of diversity in the gene pool.



That's been vastly over reported, the default M:F ratio is actually ~1.03-1.05 men to 1 women. Men are however significantly more likely to die every year (other than 10-12), and the age gap at marriage means even more men die before finding a spouse. Add on women are more likely to remarry than men and you can have large gender gaps without destroying society.

PS: China M:F ratio is 106 to 100. By comparison India is 108 to 100 but 90 to 100 over 65 the population is simply young. https://en.wikipedia.org/wiki/List_of_countries_by_sex_ratio
