He is talking of threads as an abstraction. Not operating system threads, more like green threads. Different languages call it different things, so I'm fine with the word thread. He even explains that he doesn't mean operating system threads, so your response doesn't make complete sense to me. I've always wondered why Joyent built Node.js when they already used Erlang. I've tried to research it but there seems to be no articles about it. It's something I would really like to know because it seems like most people's uses for Node.js could easily be done in Erlang, and they were already using Erlang so did it fall short in other important ways? Or Stackless Python if you don't like goofy languages. Both existed when Node.js first was released. Nowadays Go can fill in many people's use cases too. And I would also argue that green threads are higher level than CPS. So there has to be a reason to use Node.js other than its async stuff.
