> how all the popular dynamic languages have slowly become statically typed

Count the amount of `Any` / `unknown` / `cast` / `var::type` in those codebases, and you'll notice that they aren't particularly statically typed.

The types in dynamic languages are useful for checking validity in majority of the cases, but can easily be circumvented when the types become too complicated.

It is somewhat surprising that dynamic languages didn't go the pylint way, i.e. checking the codebase by auto-determined types (determined based on actual usage).

Julia (by default) does the latter, and its terrible. It makes it a) slow, because you have to do nonlocal inference through entire programs, b) impossible to type check generic library code where you have no actual usage, c) very hard to test that some code works generically, as opposed to just with these concrete types, and finally d) break whenever you have an Any anywhere in the code so the chain of type information is broken.
