Robot sex will only fuck up society even more. Instead of fixing the actual underlying issue, which is the completely fucked relationship between the sexes, it provides a placating substitute. Like you aptly summarized, it's porn 2.0.

If men can get an acceptable sexual experience from these robots, then who would care to put up with women?

I imagine many people might not, if the bots are good enough. But there's nothing to celebrate about that development. The union of the male and female is a fundamental dynamic both for the individual and society; from the destruction and degeneracy of that dynamic follows more destruction and degeneracy. Don't we see that here on TRP every day? the thousand cock stare, inceldom, the failure rate of marriages where wives have had many sexual partners... that shit doesn't stay confined in its own little corner, you can't insulate it from your life. Sexuality is a more fundamental mechanism than almost anything else, on the same level as the drive for food, shelter, physical safety.
