The thing is I don't want ruby to meet the fate of javascript. Javascript community is much bigger than ruby will ever be. They had to manage so many people writing too many code, and invented tool for them so they can contribute without making them learn completely new programming language. Easier to jump in. And I should mention typescript types is much better than what we have in rbs/sorbet. They have types inside language, without annotation like what we have separate sig DSL in ruby.

We should invent new programming language typed_ruby and give him separate life, and then history will prove us whether it should have been implemented in the first place. But not try to push it into stdlib and persuade everyone else that it is the right way to go.
