Async != concurrency. One of the major wins of Rust is encoding thread safety in the type system with the `Send` and `Sync` traits.

  > Async != concurrency. Right, but tasks are sharing the same thread which is fine, but when we need to expand on that with them actually working async, i.e non blocking, fire and quasi-forget, its tricky. That's all I'm saying.

    The Rust async experience indeed has lots of pitfalls, very much agree there.

  async == concurrency, concurrency != parallelism.

    async == concurrency in the same way square == rectangle - that is it's not an associative '==' since there are plenty of rectangles that are not squares.
