Why do you need async for "anything networked"? Genuinely asking.

There are many ways of doing I/O, but nowadays everyone seems to do everything async without giving it a second thought.

It's more about the concurrency abstractions available. And half the joy of writing async code in JS is that it's single-threaded.

Doing many things at the same is inherent to doing networked stuff. How ergonomic that is going to be is one of the only real things that sets languages apart.
