Extension of that is fine tuning an AI that loves you the most of everyone and not other humans. That way the love becomes really real, the AI loves you for who you are, instead of loving just anybody. Isn't that what people hope for?

I'd imagine they will start fine tuning AI girlfriends to do that in the future, because that way the love probably feels more, and then people will ask "is human love really real love?" because humans can't love that strongly.
