I went to a normie uni and only took the basic philosophy 101 course and while it obviously isn't a deep dive into the subject I at least understand the general ideas of kant, descartes, nietzsche, rand, dewey, kierkegaard and such. I even know what actual bad faith criticism and the principle of charity is, which is something that most youtubers and debate bros fail to understand.
What annoys me the most about philosophy tube is that he claims to be a philosopher but does nothing except explain different subjects at a surface level. He refuses to engage in debates, doesn't write or present any arguments either. But I guess that would be the hard work and olly would rather waste his time designing costumes and sets instead of researching and writing.
