If you want my opinion, I think LLMs can be pretty good at generating simple code for things you can find on stackoverflow and require minor adjustments. Even then, if you don't really understand the code you can have major issues.

Your site is case in point of why LLMs demo well but kind of fall apart in the real world. It's pretty good at fitting lego blocks together based on a ton of work other people have put into React and node or the SSE library you used, etc. But that's not what Karpathy is saying, he's saying "the hottest programming language is english".

That's bonkers. In my experience it can actually slow you down as much as speed you up, and when you try to do more complicated things it falls apart.
