I've been a professional C, Perl, PHP and Python developer.
I'm an ex-sysadmin from the late 20th century.
These days I do more Javascript and CSS and whatnot, and promote UX and accessibility.
During your work, probably you faced a function that you asked yourself: "-What the hell is even that?"
Yes, but that's not so much because I didn't comment the code, as that I didn't write clean, readable code in the first place. If the bit of my wetware that needed to light up at the time to tell me to comment it had actually been doing its job I'd have written it better anyway!
Mostly, I'm on your side in this. I like commenting things. I like having a standard doc comment at the top of every function, even if it's "obvious".
However, I've had colleagues who don't, and their arguments are usually something like, "now you have to update two things", i.e. whenever you make a code change you need to make sure the comments and documentation match, and it's way too easy to forget. In fact, how many times have you seen the same comment repeated because someone's copied a component from one file to another to use as a kind of boilerplate, even though it has an entirely new purpose now?

We're a place where coders share, stay up-to-date and grow their careers.
