Well put. It still puzzles me that promises and/or CPS don't have a greater adoption in the JavaScript community. I guess that what happens is that the concept of a callback is a very easy to understand one, but a system becomes more complicated and cumbersome (exponentially, I would say) with every new callback that is added to it. The real problem comes when creating big async applications in JavaScript based entirely in callbacks, as it is the norm now specially in NodeJS projects. Using callbacks to build complex applications is a sure way to un-maintainability.
