There's a flood of these sorts of article at the moment, many of them, like this one, reviews of these sorts of books. Something seems to have tipped in the legacy media.
Whilst I do agree that it feels like culture is a bit 'stuck' at the moment, I'm always a bit mystified that so much emphasis is put on algorithms and tech as the only real culprit. However bad culture might be now, is it really any worse than in the late 1990s or early 2000s? I remember that as an era of near-complete cultural exhaustion, with the massive cultural gatekeepers still in control.
