Love this article. I consider the async/await function coloring to be a lot like aspect oriented programming of the 90s. It requires a bunch of extra compiler features added, it’s supposed to make a class of problems easier, and it has one or two poster child applications that always gets showcased. I cross my fingers that like AOP, after a bunch of effort/hype is spent on it, it will go away.

On another note, I work in all of Python, embedded C with an RTOS, Swift, Kotlin, Python, and Elixir. I can’t say enough how wonderfully simple reasoning about these concurrent kinds of examples is in Elixir. It’s like a whole new world (yeah, sing it). My closest second favorite was actually GCD for Apple back in the day.

But it's actually useful for scalability.

All modern IO is async. The fact that you get this easy to use API to make an app more scalable is a ridiculously good deal.

Now, if you don't really need that, then it just looks like pointless extra work.
