> This article is about async/await.

It is not. It tries to address async/await part-way through, but it does so without the context of 10 years of successful async/await usage in javascript, the language it's criticizing.

> Threads do solve this problem because they are just regular functions being called by other regular functions. They don't require the entire function stack to be `async` in order to work.

This is fixating on syntax: it would be trivial for all functions to simply be `async` by default and for all calls to an `async` function to automatically `await`. This might "fix" the coloring problem as you describe it but I argue wouldn't meaningfully change anything.
