To the contrary, I believe that process improvements around a programming language will be more important than bare language features going forward.

If I were to build a language, a headline feature would be a package repository that enforces best practices (e.g. it should outright refuse to publish a minor version upgrade that breaks the ABI).

So what happens if you have a project that uses more than one programming language? (And what project nowadays doesn't? E.g., Python + C++ + Javascript + HTML + CSS is as simple as it gets for a larger-scale project today.)

Any 'process improvement' scheme will necessarily need to be language-agnostic to achieve popularity.
