You&#x27;ve been in discussions on this forum where I slam both C and C++. I&#x27;m clearly against it unless I absolutely <i>have</i> to use it due to its issues. That&#x27;s why your strawman is more amusing than most. My actual argument was that new tools are usually unstable in terms of features, implementation bugs, and (with compilers) performance. So, default recommendation for mission-critical apps are mature tools whose strengths and weaknesses are well-understood so pro&#x27;s can use them robustly.<p>Back to beta-phase claim, you&#x27;re saying the core features and compiler of Rust are no longer in development or testing? Totally stable now with only extensions, library features, and optimizations being added? If so, that&#x27;s good news and I&#x27;ll drop that claim in the future. Otherwise, it&#x27;s in the beta phase. Another hint would be existence of any bugs with core functionality in your compiler or libraries.<p>Again, though, if the spec and core functionality are frozen with all bugs fixed then I won&#x27;t call it beta. Is it there yet?
