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.
I don't really see how my site is "falling apart in the real world". It is a real site used by real people in the real world. It is not falling apart.
I am agreeing with you, LLMs can be useful for simple code generation where you're primarily plugging existing components together.
And in any case, you are moving goalposts. OP said he had never seen anyone serious claim that they got productivity gains from AI. When I claim that, you say “well it’s not the next level of abstraction for all SWE”. Obviously - I never claimed that?
