I think what he's really getting at is that user-space threading is effectively underrated. There are models for cooperative threading using coroutines, such as Ruby's Fiber that are underutilized. One just has to be careful to make sure all blocking operations will suspend and swap coroutines.

"Userspace threading vs. event programming" is a fake controversy. Event advocates tend to be userspace/nonpreemptive thread advocates.

  Not always. Node.js is very opinionated on advocating a closure-based model versus user-space threading.

    "Closures" and user-space threads are two different approaches to the same end-state, which is code that is scheduled on I/O events instead of timeslices, and that implicitly manages all the state involved in the request.
