Just because it's strange and different doesn't mean it's insanity. I likened it to pets because of the grief but there's also religion. People are weird and even true two-way social relationships don't really make a lot of sense practically, other than to feed some primal emotional needs which pets, AI boyfriends, OF and gods all sort of do too. Perhaps some of these things are still helpful, despite being "inasnity" while others might be harmful. Maybe that's the distinction you're seeing, but it's not clear which is which.
