I would like to give a shout out to the Pony Lang community;

Pony is a very interesting language, especially for use-case where Erlang shines. But unlike Erlang, Pony has a focus to guarantee that there are no race conditions. Meaning the dreaded "shared and mutable state" is not a thing. It accomplishes this through a remarkable type system, in my opinion superior to Rust's "borrowing".

I am (slowly) implementing one block programming platform using Pony, and love it.
