No, actually that was just javascript. Programming environments with threading models don't have to live that way. Separate threads can communicate through channels and do quite well for themselves. See how it works is, you do something like let data = file.read(); and the it just sits there on that line until the read is done and then your data has the actual bytes in it and you just use them and go on with your life.

That's exactly how async/await works, except that it translates to state machines under the hood which gives you great performance. No need to mess with threading models, at all.
Yeah, Rust's async/await and lightweight threads are functionally very similar. Function coloring is a problem with async/awaitt, though (for now?).
Until you need cancellation
One rarely really needs that.
Maybe you are both right but your scales are orders of magnitude apart.
