Still saves a ton of time from learning from either somewhat related tutorials. Garbage courses. Or digging through the modern spam infested web.
It's a decent tutor, never said that it's perfect. I will not hesitate that using it as an assistant has bumped up my productivity and learning by roughly 50% when it comes to programming.
Of course, it has it's myriad problems, specially in bleeding edge fields like AI development with libraries iterating sometimes nightly. As well as it's trend to not exactly teach, but instead answer your specific question. So you still need to have some initiative and still rely on a few human resources.
HOWEVER, I do agree that blindly copy pasting code from an AI is a TERRIBLE idea. And all the buzz about AI developers seems like a disaster waiting to happen (and it certainly will!).
