Depends on in what ways. Love isn't a singular thing and it isn't even particularly consistent. Some lovers connect purely hedonisticly, some are partners in effort, some are emotional anchors, some are domestic assistants (in both directions if it isn't toxic), some are fellow explorers, some are parents and others aren't. Most relationships are spread across a lot of these categories and often times friendships also cover some.

If you're considering a world where AI fulfills all of these needs that's a potentially extremely scary world... but if AI is supplementing, I think that's healthy. It's a tool and we use tools to make our lives easier, instead of a couple essentially needing someone working full time to maintain a house we have tools for that... instead of raising a child entirely on your own we have day cares and baby monitors and pediatricians... for hedonism fulfillment we have vibrators, other sex toys and erotica, relationships have evolved so traveling with a friend outside of your family (once extremely taboo) is now acceptable - as are open relationships.

How we interact with one another is always evolving and if AI can make that more positive that's a great thing. So don't think of it as going out and purchasing an AI waifu out of the blue one day, think of it as a slow evolution... maybe a private AI for journaling that helps you when you need to talk something out... maybe an AI assistant to help you manage your finances... things that take away the busy life work that gets in the way and let's us focus on connecting with one another.
