I am not blaming
tech - I doubt dating has become harder when everyone got mobile phones -, I am blaming
the adtech industry which is well-known for shady practices, dark patterns, and other UX/algorithmic shenanigans designed to maximize engagement on their apps, regardless of whether the app users derive personal happiness from it. It's not controversial, even on HN where half the demographics is on adtech jobs, to remind people that the goal of dating apps is to keep you on them, and if you find a fulfilling relationship, you won't stay on the apps, so they are incentivized to make sure you
don't find a fulfilling relationship. Hence the headline: dating has become harder.
As for Houellebecq, his books are mostly about how gen X dudes feel empty inside - the crude prose and extremely plain writing style make for an interesting couple of books but there's very little beyond it. He also somehow makes the argument that men would be somehow less frustrated in places where people have less agency in their dating choices, which is an interesting, if unproved assertion - it would be nice if any citizens of the Islamic Republic of Iran, or Algeria, or Pakistan on HN could chime in and say if they agree with it.
