When I read about people using AI to write code, it always seems to me that it would be a lot faster and less hassle if they would write the code themselves, without even considering the fact that it would give them more experience and make them better.

I have used some of those tools myself, and for the code that I could use help of an AI tool, I, again and again, receive junk: code that looks plausible but that does not compile, uses apis or libraries that do not exist and so on. In the end, it just made me waste time.
