Steven Sinofsky wrote a great post on Re/code describing mobile payments in Africa. There is so much important information in here and I’ll probably have to read it several times to fully appreciate it.
Here, I just want to mention one thing.
That is, “Necessity is the mother of invention”.
Importantly, necessity is very different depending on where you live. If science & technology were essential for invention, then the U.S. would dominate globally. That is not the reality.
Innovation happens everywhere, in places where you least expect it, regardless of technical prowess.
Innovation does not necessarily “trickle-down” from the U.S. In fact, it could trickle-up if we gave it a chance.
