"Where cognitive energy would need to be spent to work out your bug, instead of copying and pasting the error."

I am pretty sure I would have gotten higher grades if I had known about StackOverflow in college. There is definitely value in figuring out things for yourself, but at the same time, staring at a C program acting differently every time because you didn't understand pointers from Day 1 and your dataset kept getting randomly overwritten, only had me learn a deep dislike for C programming.
