Typescript is so good I'd love to see Python, Ruby, PHP, etc. and every other dynamic language steal at least half of it. Python already tries, I think it was t

  Sorbet is pretty good in Ruby, there are rough edges but for that you have good escape hatches so you don't have to work full time for the type system

    In my experience, in an RoR codebase, the dynamic-ness of rails severely reduces its utility to only enabling better auto-complete (as opposed to also helping out with writing logically correct code). In typescript, when I do a refactor, or I add a feature, I will code for hours, relying solely on the typechecker for feedback, and then I will manually test, and then write unit tests. (It helps that I use discriminated unions with exhaustiveness-checks, and avoid shortcuts like `any`, to the extent possible). Such a workflow is impossible with how limited sorbet is in the RoR context. I'd still choose an RoR codebase with sorbet than without it any day of the week tho.

    In my experience Sorbet is a lot less useful than mypy and frequently unhelpful or useless, and both of those aren't in the same league as Typescript.

      That ranking of type systems matches my experience a 100% too.

  PHP already has an opt-in type system that's runtime safe (ie it's not just compiled away like in TS). The major piece of the puzzle missing is generics support, but other type handling is already there.
