I know this sounds sarcastic but I really mean it: For years everyone has been monastically extolling some variation of "the best code is deleted code". Now, we have a machine that spits out infinite code that we can infinitely delete. It's a blessing that we can have shitty code generated that exposes at light speed how shitty our ideas are and have always been.
A nicer framing is original ideas and original thinking in general is very hard and doesn't come around very often.
Steve Jobs once said a thing about the belief that an idea is 90% of the work is a disease. He is and was absolutely right.
