It always works best when layering on top of good human code. The thing is, you start to run out of that as you lean in. Tricky.

Why? I keep asking for examples of LLM being used to make code more simple and elegant (which I would say is adjacent to making software better, if not more secure), and never get a reply, not a single one. I'm not claiming it doesn't exist, I know it must exist. If only via a lots of careful massaging of system prompts and harnesses, even if it takes too much effort to be worth it, I would like to see it.

Of course people can't share internal examples, but this is all over the world for many months now, where are the open source examples? Not "something new someone couldn't have done before", but someone making their precious even neater (while also adding things to it, but not primarily). Put differently, can LLM delete code, can they curate it well, can they not write weird comments nobody wants or needs, that sound like echoes of the user prompts and responses to them, but just explain tricky parts of the code, like a human would?

Also, IMO a VERY useful thing to learn about a tool or a chemical or whatever is, "what happens if I keep applying it to the same small thing over and over?" -- because that's the level of scientist I never evolved past, the kind of stuff you do as a kid -- , whereas a lot of this seems to be more about how it feels to apply it here and there until it looks good, and then move on and never look back. Which really isn't much at all, especially given we're such a short time in. I mean, how useful were mugs made of lead? Are people aware of the (in hindsight) insane things that were done with x-rays as those were invented, before the potential for harm was known? I bet they had a great time playing with that stuff, for a while.

What if in 5 years it turns out that a few years ago, LLM got into this habit of implementing certain things in a certain way because it seemed the best to "them" (the training, whatever), but there's a security issue with that -- what do you do? You can only let more agents loose, and hope they don't miss anything, because you cannot even do something like "patch PHP" (which is not my thought, Casey Muratori mentioned that in on of those podcast things).

Fully leaning into LLM doing as much of the coding and understanding as can be handed off to them seems insane to me, I don't mean this to offend though. It just does, like suggesting we go to Mars, because everything is better there, and to do that, we have to blow up Earth. Or saying to magically be able to fly from now on, we need to saw off the branch we're sitting on. Even if I thought life on Mars was the future or that we could fly, if we just thought of it the right way, this isn't a way forward IMO.
