It's an interesting question to think about what effects we'll see when humans get almost exactly what they want. I'm thinking virtual reality + sensory overload, sex bots, etc. I'm not seeing the overwhelming evidence that people will be the exact same with significantly different experiential inputs (VR, porn) and neurochemistry (e.g. higher intensity of orgasm). Sex is involved in a lot more of our lives than just the act of sex. I'd rather we get a better understanding of how this all works before rushing mindlessly into a culture of maximal pleasure for its own sake.
