I find the argument about reduced diversity to be way too optimistic (or pessimistic ?) about people’s will and might to change their genes.

To draw a parralel, esthetic chirurgy is wildly available at relatively reduced risks, and it’s not like every bloke and their dog goes to have a face lift, even if it’s understood that a better appearance would have benefits.

Or even thinking about the core group of people who refuse to vaccinate. There’s just no way a medical practice is applied to the totality of a population, even by law.

Right, but society has a conflicted history with beauty - some parts of our culture like and reward beauty, other parts curse the vain and superficial - and especially with people making uncommon efforts to improve their looks.

Not so with being born charismatic, tall, smart, healthy and with a full head of hair.
