Overall, I think the whole reactive programming style such as node and async python are mistakes at this point. They come at too high a cost for code complexity and maintainability. Synchronous style was always superior with only one flaw, using OS threads. But now there are solutions both existing and upcoming such as Go and Java Project Loom that fix that one flaw. I don't see much appeal in the reactive style at this point.
