These are actually two parts of the same positive feedback loop.

Young men satisfy (in emotional sense) themselves with chatbots, lose ability to communicate with young women, thus young women see fewer young men they can communicate with, turn to chatbots, thus young men see fewer young women able to communicate and so on.

I would even say that this in some sense started with young women, not because I’m an incel or something, just drowning themselves in all kinds of romantic fan fiction etc is something girls apparently do more. And even romantic chatbots are not necessarily more accessible\understandable for young men, - despite all the social legacy girls can be quite tech-savvy when they want to find, say, some anime series. My sister unironically could understand some Chinese text because it was easier to find something on some Chinese sites (I’m not mixing up China and Japan here and the series were Japanese), she’d also have plenty of scary Chinese-style Chinese-language software installed under her user.

Why did I type this last paragraph, I wonder.
