I think its a bad take because "Developers are not Idiots" and "be disciplined" are not good arguments. Its just choosing to ignore the problem rust solves.
I am fine with ignoring the problems that rust solves, but not because I'm smart and disciplined. It just fits my use-case of making fast _non-critical_ software. I don't think we should rewrite security and networking stacks in it.
And rust doesn't market itself as small and simple scripting language?
Choose the tool that fits your usecase. You would never bring wasm unity to render a static html file. But if you make a browsergame, you might want to.
