What the hell are they doing in bugfixing an UI bug, when they are “not qualified” to write a test for it. Anyhow, not competent enough for the codebase you’re working on - check.
Does the name "Dan Luu" say anything to you? Do you know his blog ?
In general, for Dan Luu I wouldn't assume he is not competent enough.
And besides that, what is the point of LLMs / GenAI if you need to be an expert in everything it touches to handle it correctly? If you are an expert, you can already do it yourself.
Also, if one needs to be an expert in every topic to get good or even acceptable results, this creates more doubt that the "intelligence", "reasoning", and "capabilities" of these things are in reality the intelligence of the user, since he does the real work of discerning fabrication and accidental good output.
That's actually a disadvantage of Rust: Because the Rust compiler is written in Rust, it is hard to bootstrap on new platforms. Which is for a systems language used to build kernel device drivers a serious limitation, and also makes it harder to tackle Thompon's "Trusting Trust" problem.
Better to compile the new language to C first, which compiles and runs even on a smart lightbulb.
This does work well. It is how C++ was created, and even some Lisp implementations go this way.
