This is AI slop. The script is the sort of incoherent rambling an LLM would produce; the topic is like some amalgamation of popular youtube clickbait topics; the video clips, at least in part, are obviously AI generated; and the dude probably hides his mouth because otherwise, it would be super obvious that it's actually an AI voice talking.
I watched this originally a bit groggy and it almost felt like I was having a psychotic break. This should have a CW for possibly inducing existential angst about being the only conscious human being in existence, and the comments here aren't helping. I'm starting to think that hexbear is an elaborate AI-fueled prank at my expense.
