Well the game has also changed for dynamic languages. Writing JS or Ruby with a powerful IDE today isn't what it used to be 5-10 years ago and it will keep getting better. The tools and linters will become smarter about catching silly typos. It will never be like writing in a compiled language but the gap will narrow. Also - I don't think we'll ever agree on any language. Sure, some languages will be dominant - Java maybe or Rust or whatever, but there will always be room for alternative approaches. Humans don't fully agree on much.
