I'm old enough to remember a time when we didn't have to fight misinformation because of a thing called editorial oversight. Basically, the rise of social media has flattened the landscape of publishing, allowing any misinformed rube to spout whatever nonsense they want, without any oversight from a knowledgeable, responsible professional, and reach a sizable audience. And it's entirely possible that I'm only old enough to remember that because I got vaccinated.
But finally the landscape seems to be getting a bit better, which is great because lives are literally at stake.
