Philosophy grad school dropout becomes YouTube sensation taking on the weird and reactionary corners of cyberspace

That's Natalie Wynn, recently profiled in The New Yorker.  She had previously been a PhD student in philosophy at Northwestern, clearly in the "Continental" side of that department judging from some of the things she says about philosophy in her videos.  She is genuinely quite funny at times (her humor is very clearly not "politcally correct"), and puts a lot of work into researching her topics (and producing her videos):  see, e.g., her explanation of "Incel" culture on the Internet, or her takedown of Jordan Peterson.
