Another example is "if you haven't memorized the entire documentation, you're too incompetent to use this software". I don't think it works that way nowadays, especially when software X has dependencies Y and Z, so you'd better cram their documentations as well. The other day I was reading this little rant about Gitlab and how painful it is to update. According to the snarky responses, it's possible to update it if you've RTFM. Which is true! But it reveals this belief that doing a lot of unnecessary work and retaining a lot of noisy facts somehow makes you a better person.
