> This issue is political and not so much technical as Typescript demonstrates how you can add a beautifully orthogonal and comprehensive type system to a dynamic language, thus improving the language's ergonomics and scaleability.

How does typescript demonstrate this?

I don't see how typescript is different from Python in this regard. Typescript compiles down to JavaScript, which like Python is dynamic. So at runtime nothing prevents you from calling a function written to take ints with strings. In fact, JavaScript has even worse typing than Python, so I imagine it's worse.

Typescript demonstrates that you can have a fully dynamic language but also provide a type system which can support as much (or as little) type checking as is appropriate or desired.

I can take my chances in Typescript by just using 'any' everywhere but if I do want to constrain variables to particular types, the compiler will fully support me and provide guarantees about the restrictions I've specified via the type signatures.

It sounds exactly the same as Python with pyright or mypy. A novel approach is taken by Elixir, which actually makes sure the compile time types match runtime types. That is , you can't call a function with an incorrect input type at runtime https://elixir-lang.org/blog/2023/09/20/strong-arrows-gradua...
