The articles isn't really about grad school. It's just the headline. The article is about how the internet allows non-experts to confidently assert inaccurate information. It suggests that we scrutinize the actual credentials of the people giving us that information, and go to the original source whenever possible. It also suggests that we all cultivate humility, and remember that we are not experts because we watched a video or read an article. So that's what a person is to do. According to the article. BTW, Here's my advice for cultivating humility on Hacker News. Go do a search for threads about FTX, Theranos, WeWork, and Moviepass from a few years ago, and see what the average Hacker News user had to say about them. You'll find skeptics, of course. But also plenty of users absolutely certain that there's something to these companies, and that the founders are merely playing a game of 5d chess, or something like that. It's a good reminder that we can all get things wrong, even when we're really sure about something. And a reminder that nobody is immune to being duped.
