This piece lacks a good definition of "junk info". The closest is this: >"Common types of junk info include gossip, trivia, clickbait, hackery, marketing, churnalism, and babble. But in fact, any information that you can't use is junk info. A typical example on social media would be a photo of a freshly cooked burger, captioned with “Look what I just made!” but posted without a recipe so you can't even recreate it" There's huge gap between "info that you can use" and the examples given of "junk info". I enjoy reading Wikipedia entries on scientific topics, but I can rarely "use" that info in any practical sense
