This article is about async/await. The function coloring problem arises when you have async functions. Regular functions can't call async functions. You have to hoist them into async functions in order to do that.
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.
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.

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.
