Well said. I am also thinking, we have so many apps in our lives nowadays and they get update often enough. Most people would not want to explore all the different options and features.

Even tutorials are skipped and forgotten. Need to keep it simple as much as possible.

I imagine in the future, all apps would be self-learning / machine-learning according to the users frequent usage - to the point it would be even smarter than Google Now or with a Watson-like API in the back of each app.
