It's questionable how true that is when it comes to human relationships, which is obviously what I was suggesting with the metaphor.
Many people have social issues or mental health issues that cause them to be alone and loneliness is an ever increasing problem due to all kinds of factors beyond one's control. Many people will see AI as better than nothing and get some of their social needs fulfilled via it...some already are.
I don't want to be crass, but likening it to a sex toy except for relationships seems pretty accurate to me. It's fulling a need that otherwise wouldn't be fulfilled.
Ignoring that I mean let's be real for a second, how is an AI fundamentally different than an internet friend you've never met or seen? The humanity of the other person? What if the AI behaves just like a real human would?
