> I'm much more comfortable with threads

The example code shown in the first few minutes of the video is actually using regular OS threads for running the async code ;)

The whole thing is quite similar to the Zig allocator philosophy. Just like an application already picks a root allocator to pass down into libraries, it now also picks an IO implementation and passes it down. A library in turn doesn't care about how async is implemented by the IO system, it just calls into the IO implementation it got handed from the application.

or you can pick one manually. Or, you can pick more than one and use as needed in different parts of your application. (probably less of a thing for IO than allocator).
