I kind of disagree with the article's premise - that the fact that Go uses async/await like Js and C#, but presents them as green threads is a good thing.

Imo it creates false expectations in programmers, who are surprised, that long-running compute code doesn't get preempted, since the compiler doesn't insert preemption points.

It also robs us of the possibility, of writing event-driven UI applications, where one can make an asynchronous call on the UI thread safely, which will get marshalled back to the UI thread.
