I don't really understand the "doomscroll" discourse to be honest. For one doom is sort of an appropriate mindset for a solid chunk of history. I wonder what internet optimists would have written about doomscrolling in the 1920s if the web had been around, with the world on the verge of multiple major conflicts. I can only imagine some new Stephen Pinker book going "guys, it's going great, look at all the inventions!"

People who were dooming about zoonotic viruses over the last few decades were right and we ought to have listened to them, climate change doomers from the 70s or 80s certainly look prescient and will increasingly more so in another few decades.

Rather than taking a three monkeys approach of "see no evil/hear no evil" I think a healthy dose of doom creates an appropriate sense of urgency to problems we are otherwise prone to sleepwalk into.
