Most important aspect of C is its portability. From small microcontrollers to almost any computing platform. I doubt that any new version of C will see that much adoption.

If I want to live on cutting edge I would rather use C++2x or Rust rather than C.

Am I missing something? What benefit this supposedly modern C offers?

these features will eventually trickle down into the mainstream, kind of like C11 is doing at the moment

also, unless you're targeting embedded or a very wide set of architectures, there's no reason why you couldn't start using C23 today

Or in other words, for embedded and existing code: most use c99, some use c11 and nobody uses c23 until at least 10 years from now.

This depends on the platform. Many embedded systems are based on arm these days and have modern toolchains available.

I cannot remember the last time I saw C99 used. C codebases generally use C11 or C17, and C++ code bases use C++20

Most devices that are 6+ years old (as far as I can tell) use C99. If not C89. And/or C++17, if that.

That's A LOT of devices out there. A lot of which still get maintenance and even get feature updates (I'm working on one right now, C99).

So the claim that "C codebases generally use C11 or C17, and C++ code bases use C++20" intuitively sounds like totally untrue to someone working in embedded C/C++. I've been doing this for 15+ years and I've never touched anything higher than C99 or C++17.

If you're talking about gaming, sure. But that's not "C code bases generally".
