An experienced human can write code better than an LLM for low level tasks almost 100% of the time, the only problem is its REALLY slow for a singular person to write code when compared to like an LLM running at 600 tokens per second or something. The best combination of the two is (in my opinion) running claude on manual mode cus if it does something really bad you can either fix it yourself or reprompt it, but there is a LOT of active things you have to be doing.
>Nope. haven't done it. But I have done things more complex then language design. And I can't show you because my employer owns it. But FYI language implementation follows very common patterns and this makes it very very easy for LLMS to create one. A beta of a language can be done in about a week.
its not about the fact that the thing you are doing is "more complex" (in my humble opinion the only thing more complex than language design is building an OS) but its more of the fact that if the LLM writes one line of code that is not like optimal for performence, your language will like leak memory or it will run really slowly, or something will happen suboptimally. you cant just leave it autonomously for large periods of time (I have tried and regreted this) but you can still use it, as long as you read over and esnure that the code is optimal. if you dont do that we are just moving backwards in time and the code you write is very unmaintanable, slow, leaks memory or is volatile, and impossible to scale up or down.
