How badly has #misinformation been normalized? An increasing % of people believe the unhinged idea that the COVID vaccine killed more than COVID. 27% think true‼️ ONLY 39% know definitely false‼️ Reality: COVID killed > 7 million. Vaccine saved millions & severe adverse reaction extremely rare.

Sure, AI writing has some recognizable tics (but I ain't giving up my em–dashes!). But think this piece is overly optimistic about our ability to spot AI writing. Most studies suggest we can't. And AI only gonna get better – ugh. How to spot AI writing www.economist.com/culture/2026...

So much upsetting about the Fauci attacks. But it also demonstrates the COMPLETE absorption & normalization of hardcore lies and conspiracy theories by the political right (alas, same here in Alberta). Reality irrelevant. Rage & grievance dominate.
