Neither of you talk about what sort of machine you're sitting on. Back when I used a netbook, I'd agree with you, for developing quick off programs, the compile times are horrible. But as someone on a workstation now, compilation times are the least of my problems, and disk space is more of a concern for me.

You also don't share what LLM you use, some of them reason a lot, some of them nothing, some a bit. Again, personally I use LLMs with their maximum reasoning always, trading quality for speed/waiting every single time, and even compiling the Linux kernel would be faster than most LLM responses I get nowadays, for me, on a workstation.
