I’m not so much worried about the functionality of the code, but rather the maintainability. A lot of code was written, by a person long ago, copied together from forums online refactored by people, who didn’t understand it, but at least at some point someone understood it good enough to create it.
I find the idea worrisome, that we will deal with code no one ever understood, it’s just kind of there and seems to do what we want, and now you have to change it.
It is sadistic, kids are sadistic.
I believe this Vsauce video explains the phenomenon I mean (I have not watched the video and can’t right now).
