That's not true when the topic is operating system kernels.

OS kernels? Everything from numpy to CUDA to NCCL is using C/C++ (doing all the behind the scene heavy lifting), never mind the classic systems software like web browsers, web servers, networking control plane (the list goes on).

Newer web servers have already moved away from C/C++.

Web browsers have been written in restricted subsets of C/C++ with significant additional tooling for decades at this point, and are already beginning to move to Rust.

There is not a single major browser written in Rust. Even Ladybird, a new project, adopted C++.

Firefox and Chrome already contain significant amounts of Rust code, and the proportion is increasing.

https://github.com/chromium/chromium : C++ 74.0%, Java 8.8%, Objective-C++ 4.8%, TypeScript 4.2%, HTML 2.5%, Python 2.4%, Other 3.3%

https://github.com/mozilla-firefox/firefox : JavaScript 28.9%, C++ 27.9%, HTML 21.8%, C 10.4%, Python 2.9%, Kotlin 2.7%, Other 5.4%

How significant?

		According to https://4e6.github.io/firefox-lang-stats/, 12%. I would love an updated version of https://docs.google.com/spreadsheets/d/1flUGg6Ut4bjtyWdyH_9e... (which stops in 2020). For Chrome, I don't know if anyone has compiled the stats, but navigating from https://chromium.googlesource.com/chromium/src/+/refs/heads/... I see at least a bunch of vendored crates, so there's some use, which makes sense since in 2023 they announced that they would support it.

So, written in C/C++? It seems to me you're trying to make a point that reality doesn't agree with but you stubbornly keep pushing it.

		> So, written in C/C++? Not in the sense that people who are advocating writing new code in C/C++ generally mean. If someone is advocating following the same development process as Chrome does, then that's a defensible position. But if someone is advocating developing in C/C++ without any feature restrictions or additional tooling and arguing "it's fine because Chrome uses C/C++", no, it isn't.
