A language doesn't need to be used in foundational software to be relevant or useful. Go isn't built in the OS either, but its still used by lots of developers to write useful software. This might be controversial, but I think its fine for small languages to exist, with small followings. Nobody will ever make a browser in Haskell, but its still a work of art. Nobody uses Elm, but React wouldn't exist without it. And so on. Rust is useful on its own. But its also already inspired the C++ language committee to start talking about memory safety a lot more seriously. Thats a big deal! I'm delighted that languages like Zig exist. If for no other reason than to show that if you're dedicated enough, a lone hobbyist can still invent a language and make it good. (I wish that were still true for web browsers.)
