"Your own personal experience is a common story, but doesn't suggest a root cause."
There was at least one root cause for me. I don't really enjoy talking to women anymore. Not because I don't like or want one in my life. It was just something that was simply....not enjoyable. I met many that loved playing games, being openly hostile, or were just jerking me around for fun. I tried many different things over the years, and always worked on my assertiveness and confidence as best as I could. But there was a point where it became exhausting and I started to see women as simply more work than it was worth. I understand that plenty of men may struggle with this, meet the right person, and get past it. I am confident that if I had met someone, maybe that would have opened that door again. But in the years that I was trying it, I just couldn't take the negativity, games, and bullshit.
I also agree that women scold and shame men because they have had terrible experiences, and then assume all men are shit. This has done enormous damage, which is what you're getting at as well. People are busy with their lives. If a demographic shits on you enough, you'll just find something else to do. The problem is still there, festering.
But, having an AI companion? No way. I know too much about technology. I know it isn't real - and that was why primary reason for walking away from women - because it wasn't real.
