It's not about not crashing. C lacks memory safety, which leads to many bugs, many of which are security vulnerabilities. Memory safe languages such as python or rust just don't have those problems. The vast majority of languages are memory safe but only C is to-the-metal fast. Well, until Rust came along.

You can still crash voluntarily via abort! and panic! if that's what you prefer when your program encounters an error.

You like security vulnerabilities? I don’t think we are talking about the same thing at all. It’s perfectly easy to make Rust “crash” or log errors when it does the wrong thing, and to write unit tests for it.

Memory errors and threading bugs are never ever something you want.

What is the right problem? What would you _like_ Rust to be solving?
