Seriously, this is everywhere lately. In my view, one viral moment can make someone an "expert" overnight, even if they don't know much. It's a weird pattern now.
Actually you're missing the point. Going viral means you connected with a huge group of people, which is a real skill in itself. A lot of "real experts" are terrible at explaining things to normal folks. If someone breaks through the noise and gets people to listen, maybe they have something worth hearing, even if they don't have a fancy degree. Dismissing it all as empty hype is just gatekeeping.
