I agree. I think that there are two things that are missed out from the this article.

1. Programmers are lazy and will waste cycles like crazy around IO if given a chance. Core library async get's them thinking in red mode but it also get's them actually thinking in ways that allow the overall app to usefully get on with other things. Go sounds like it might be a nice exception to this but I'm not familiar enough to comment.

2. He kinda skips over the fact that threads are really really hard to work with and test (I immediately think about wasting time with race conditions that are just about impossible to reproduce or fix). Node.JS style continuation hell has the advantage of being a model that can actually be understood and made to work reliably in a way that threading, in theory can, but in practice cannot.
