Okay, yeah, I was indeed reading your original reply as a criticism of one of the people involved (presumably the security researcher), rather than as a criticism of the post title. Sorry for misunderstanding.
...what is your point? Some software (in a language that doesn't have tail-recursion optimization) used recursion to handle user-provided input, and indeed it broke. Someone wrote to explain that that's a potential vulnerability, the author agreed, and fixed it. Who here is misunderstanding how computers implement recursion?
TypeScript is a language, and traditionally languages are considered separate from their implementations. When I first saw the headline I hoped maybe it meant a non-JS runtime for compiled TS, and I'm well aware of the difference. Yes, that would be a much larger undertaking than porting the compiler to a new language, but the headline doesn't indicate how large a project this is, and Microsoft certainly has the resources to write a new backend (even a native-code one) for the TS compiler.
They did consider making environment-manipulation functions atomic; the problem is that there's simply no way to guarantee that everything that can manipulate your process's environment is actually beholden to whatever atomic interface Rust provides. I could be misremembering, but I think there was even some discussion with glibc maintainers about whether this could be made safe, and the answer was basically "haha no."
What virtual desktops do you prefer? I don't find Mac OS's significantly better, and I haven't spent much time with very many Linux window managers other than i3 (and that was years ago).
This headline is based on responses to the question "what are your biggest worries about the future of Rust", not "are you worried about the future of Rust." So of course most of the respondents answered with a concern about the language.
Marcan pretty clearly isn't saying that feature requests wore him down. He's saying that people saying "what you've built so far isn't useful" wore him down.
(Plus, your original analogy about parents and children is completely lost by now.)
