I think it's a really interesting question, but more towards: Will people stop having real relationships? The 2013 Spike Jonze film "Her" explores this a bit.

Relationships are tough because neither person is perfect. So when you have a perfect partner who says all the right things, based on a unique supermodel image, and who will never argue with you... will people just find it easier to do that?

Will the world massively depopulate because we all have fictitious dream partners?

This is the way the world ends / This is the way the world ends / This is the way the world ends / Not with a bang but a honey
