It's true. It is very hard to draw a line through what is "innovation" vs what is "iteration." All the tiny things we build sit on top of the other tiny things built by those before us, and in the grand scheme, everything is quite small.

However, this makes me wonder if maybe we shouldn't be focused on "innovating." Maybe it's not the goal (or it shouldn't be the goal). But then, what should? What should we aspire to build or create? Should we aspire to any particular thing? Maybe we should just do what we want and ignore what others have to say?

I don't really know, and I'd love to hear what others thoughts are.
