I'd also suggest that 2008 was the arrival of social media. Suddenly everyone got insight into what everyone else was thinking all of the time. Not just a little bit here and there. Everyone's innermost thoughts writ large - plus all the photographs of everyone's proudest moments.

If you're the sort of person prone to worrying about whether you're good enough, handsome enough, built enough or successful enough to be a lover - your anxiety just went through the roof. Throw in the economy and you get two related outcomes.

Rising anxiety across society including a rise in suicide rate for teens who cannot calibrate - and also the seperation of society into bubbles of ideas rather than bubbles of geography. Suddenly people are spending more time inside talking to people who are ideologically similar to them but who may not live nearby.

Some of those ideological niches, like incels and, to a similar extent radical feminism, make selecting a potential mate much harder. I was briefly friends with a very woke girl who was determined to find herself a boyfriend (someone like Idris Elba) but who treated all men with the sort of suspicion reserved for criminals. Although we don't talk any more, I suspect she is still single and still a virgin - not that there is anything wrong with this.

Social media and poor economic choices are exactly how you kill sex in the modern age. Sad for the individuals for all the reasons you've highlighted but from the point of view of the planet, this is truly excellent news :o)
