The Importance of Observables in ES20XDX

I'd much prefer to see something like the callback spec than the observable spec from what I understand. The observables from the way I understand it kind of puts a lot of the magic behind the scenes. And I actually prefer the idea that you have more of a chain, more of an explicit signal that I call this action and there's a tree of things that that's going to fire off. That's just easier for me to read. There's more lines of code when you look at I'm going to write more Lines of Code because instead of having nested dependencies, Dependencies go wide. So I kind of hope that the observables... I think it's kind of lost steam.
