I’m specifically thinking: VR, AI chatbots and even sex robots but whatever technological advancements you think apply are also part of the discussion.

I don’t think it will change much. Social stigma aside, most people will always want real human connection over something artificial. I doubt there will be a huge influx of men getting AI girlfriends and leaving the actual dating scene. The only men who’ll be doing this will be those who already struggle with dating, therefore the technology will just give them more means of escapism.
