These are only problems if you assume the person later wants to come back to having human relationships. If you assume AI relationships are the new normal and the future looks kinda like The Matrix, with each person having their own constructed version of reality while their life-force is bled dry by some superintelligent machine, then it is all working as designed.
Human relationships are part of most families, most work, etc. Could get tedious constantly dealing with people who lack any resilience or understanding of other perspectives.
The point is you wouldn't deal with people. Every interaction becomes a transaction mediated by an AI that's designed to make you happy. You would never genuinely come in contact with other perspectives; everything would be filtered and altered to fit your preconceptions.
It's like all those dystopias where you live in a simulation but your real body is wasting away in a vat or pod or cryochamber.
It could be the case that society is responding to overpopulation in many strange ways that serve to reduce/reverse the growth of a stressed population.
Perhaps not making as many babies is the longterm solution.
