It is a tool. Some tools make you more productive after you have learned how to use them.
I find it interesting how in software, I repeatedly hear people saying "I should not have to learn, it should all be intuitive". In every other field, it is a given that experts are experts because they learned first.

Other fields don't have the same ability to produce unlimited incidental complexity, and therefore not the same need to rein it in. But I don't think there's any field which (as a whole) doesn't value simplicity.
I feel like it's missing my point. Using a chainsaw is harder than using a manual saw, but if you need to cut many trees it's a lot more efficient to first learn how to use the chainsaw.
Now if you take the chainsaw without spending a second thinking about learning to use it, and start using it like a manual saw... no doubt you will find it worse, but that's the wrong way to approach a chainsaw.
And I am not saying that async is "strictly better" than all the alternatives (in many situations the chainsaw is inferior to alternatives). I am saying that it is a tool. In some situations, I find it easier to express what I want with async. In others, I find alternatives better. At the end of the day, I am the professional choosing which tool I use for the job.
Except you're hearing it from someone who doesn't have a problem handling state machines and epoll and manual thread management.
Right but how do you expose your state machine and epoll logic to callers? As a blocking function? As a function that accepts continuations and runs on its own thread? Or with no interface such that anyone who wants to interoperate with you has to modify your state machine?
And that was intuitive and easy to learn?
I find state machines plus some form of message passing more intuitive than callbacks or any abstraction that is based on callbacks. Maybe I'm just weird.
