I'm one of those, but what I mean is that there are no static types you (and the compiler) can reason about.

Moreover there's a difference between types as compiler bookkeeping, as in Fortran or C, and types as propositions about program behavior like in ML, which highly influenced modern type systems, including TypeScript, albeit Ocaml, F# and the Rust type system belong to the ML family.
