I'm pretty sure most big software projects (Windows, Linux, Chrome, gcc, LLVM, AAA game engines, ...) are still writing a lot of new C and C++. Pretty much everyone in the embedded world is as well.

As a solo programmer, I still prefer C and C++. In fact, as I've incorporated LLMs in to my workflow, I've been increasingly drawn toward C and its simplicity. A lot of the QoL features of C++ simply aren't needed when you're writing less code manually.

Using LLMs to write C feels a little silly to me. (Unless you really need C.) LLMs are still imperfect; you're still going to get a lot of UB bugs like human-authored C.

Chrome should be ported to Rust long ago. on Windows, half of the UI can migrate tomorrow with ease.
