I was watching the network traffic sent by Twitter the other day, as one does, and apparently whenever you stop scrolling for a few seconds, whatever post is visible on screen at that time gets added to a little pile that then gets “subscribed to” because it generated “engagement”, no click needed.
This whole insidious recommendation nonsense was probably a subplot in the classic sci-fi novel Don’t Create The Torment Nexus.

Almost entirely unrelated, but I’ve been playing The Algorithm (part of the Tenet OST, by Ludwig Göransson) on repeat for a bit now. It’s also become my ring tone, and if I can infect at least one other hapless soul with it, I’ll be satisfied.
