Well, Rust does fulfill these to a reasonable degree. There is obvious room for improvement, but the vast majority of languages don't even bother being a Rust successor. Instead, they take a step back and decided that what Rust is doing is too much, e.g. Zig. It's kind of irritating that everyone and their dog is coming up with a new programming language that barely changes anything when there are so many low hanging fruit. The vast majority of programming languages that people are coming up with could have been language subsets, extensions or alternative runtimes for existing languages.
