Then again, you'll just point to how awesome it is that Rust doesn't change and stays stable and easy to use for years.
It's all just rationalizations for the emotional investments you've already made.
C++'s standards process and pace haven't stopped the stdlib from being filled with bad implementations of primitives that people have to replace with libraries like Boost or custom per-vendor implementations - why do you think so many companies (game studios, facebook, etc) ship their own versions of the C++ STL, or prohibit the use of the STL entirely? Why do so many libraries ship with a C++ wrapper over a C public interface instead of the opposite? Why do binary-only libraries written in C++ so often ship with unique builds for various compilers instead of a single binary like a C library? The main answer to all of these questions is that C++ is deficient by design in all sorts of ways - underspecified ABI, low-quality stdlib specs, bad encapsulation, bad performance characteristics, etc.
C++ is just losing here.
