I'm also on the side of static typing being beneficial. I would always however consider the case at hand individually rather than reject it offhand because it lacks it. e.g. a complex distributed working system written with say Elixir or Erlang isn't easily replaced with typescript. Not all systems are better with any static typed language than any without.

Once you reach a certain size of developers, add static typing if available, e.g. TypeScript, Sorbet, etc
