I was giving advice for how to learn a subject. The text is obviously satire even without the warnings if you understand the fundamentals of ML. I'm not saying they need a PhD or something.

I have no problem with open access, and would rather journals were required to be open access. But reading brand new results that haven't had any peer review without familiarity with the field is putting the cart before the horse. I certainly don't learn a new subject by reading the hottest papers on arxiv.
