no matter how much you “love” your AI girlfriend she will never truly love you back because she can’t think or feel, and fundamentally isn’t real.

On one hand, yeah, current generative AIs don’t have anything that approximates that as a mechanism. I would expect that to start being built in the future, though.

Of course, even then, one could always assert that any feelings in any mental model, no matter how sophisticated, aren’t “real”. I think that Dijkstra had a point as to the pointlessness of our arguments about the semantics of mechanisms of the mind, that it’s more-interesting to focus on the outcomes:

“The question of whether a computer can think is no more interesting than the question of whether a submarine can swim.”
