Yeah, I can't really tell if the overall community will adopt it or not, but you may well be right. Last time I commented something about ruby not having static typing I got downvoted by people claiming Sorbet is already used heavily in production.
But either way if I'm switching off of ruby, I don't really want to go to something else that doesn't have static typing.
A few huge companies like Stripe use Sorbet. Thats really not a good representation of Ruby users though. I guess youre right, for dynamicism Ruby is awesome but if you need types just switch to a true typed language.
