Rust lacunae

ncm: as a relatively unbiased observer (liking both C++ and Rust)... your arguments are not covering you with glory here. Rust is seeing *substantial* usage -- yes, it's not more usage than the entire installed base of C++, but expecting anything of the kind is utterly ridiculous: the language is younger and hasn't had massive adoption for its entire lifetime (of course it hasn't), so its effective lifetime in terms of large-scale usage is shorter than that. But it definitely *is* seeing large-scale usage. Not higher usage than C++, no, not yet -- but ask which language is growing faster, and which language new projects are being written in, and I'd be astonished if you answered C++.
