What do you think we've missed? Do you want one build systems for all languages? There are such systems (e.g. Bazel) and they're often used for multi-languages projects, but I think reality has proven that build systems with language-specific knowledge are much easier to navigate.

I'm not sure how outlandish we're allowed to get here, but IMO we have a fundamental mismatch between application <> operating system <> CPU in terms of dependencies and trust.

Fixing this is beyond any one tool, of course :)
