But these explicitly don't mention the two best approaches he chose to ignore and even kill.

First the parrot threading model, which provided lockless safe threadpools, and second the pony threading model which provides the same on top of supporting shared refs, and forbids blocking IO. Which makes it even faster.

His talk ends with his simple approach taken being the best. Which is not only wrong but also a lie, because he was part in killing off the parrot threading model.
