I don't buy "Anywhere, anytime, by anyone" - no language can be that. Different people and different projects have wildly different needs. It looks like it tries to provide a single binary offering most of the compiler, debugger, linter, etc. on "all" platforms. Noble goal in itself, useful for some cases, but utterly irrelevant for many (most?) projects. If I have already decided to work on Linus, I don't care about Windows compatibility. And why "by anyone"? If a language is optimized for school kids, it can not be optimal for serious professionals, and vice versa.
