I'm currently reviving a personal iOS project that I last worked on almost 10 years ago. At the time, I was working under a (much younger) tech lead who was a firm advocate of the "all comments are bad" philosophy and reported me to management as being technically incompetent because I commented my code. Thank god I'm technically incompetent because there's no fucking way I could be making any sense of my 10-year-old code without those comments.

Somebody here is probably going to reply that nobody literally thinks all comments are bad, but I assure that you such people do exist in this profession.
