Programming Language of the platform

In which programming language will the platform be developed. I’ve read that you will use wasm to be open to every programming language, which I find it great but I’m asking myself in which language(s) different (key) core functionalities of the platform will be written.

Networking and Node is written in Scala.
Execution Engine for smart contracts is written in Rust.
Wasm for contracts with initial support for Rust and more compatible Wasm languages in the future.
Integration Testing of the system with Python.
