You're not "moving faster" if a typo is a runtime error and you're not "more productive" if you can't change a function signature without having to grep your codebase to find all callsites and pray you fixed them all.
Types are good, but as with anything else people take it too far. Making it your life goal to encode all business logic in the type system results in an even more incomprehensible mess than not having types at all. If the type name can't fit on one line in the error message, you've gone too far.
