I mean, it should be obvious in my reply. If you want intimacy with another person, getting some shitty simulation of it from an AI girlfriend is not going to help you get it. it's completely fake. It doesn't help you grow as a person or reach your goals. It's ultimately just keeping you from going out and doing what you need to do to get what you want. You'll never have a real relationship with a robot. You won't have a marriage, or a family. Just talking to an AI, alone in your house. We've all seen "Her", right?
The real problem, with stuff like this, and even pornography, is that our brains can't really tell the difference on a chemical level between the real thing and the fake stuff. Our brains were not evolved in a world of AI and computer screens. So you get the emotional, dopamine hit with your AI girlfriend without actually putting in the work.
