I'm talking 30-40 years+... When most of the unattractive of us will be either dead, too old to date, or have an ai robot partner.

Naturally the unattractive will die and not procreate thus not making any more unattractive offspring.

Will the population eventually stabilise?

Or will a new terrible trend like really fat calves suddenly become an attractive highly desired trait and once again the genetically misfortunate will be doomed to a life of solitude again.

I think it's really only societal changes mainly social media which are the reason we haven't naturally adapted as quickly and now the majority of us are considered unattractive.

Say 30 years ago... Almost any average person would easily have found a partner
