First, the picture you showed does not look rural to me, yet it is good to see someone wearing a Bitcoin shirt. The awareness about Bitcoin is on and I know that with time the remotest areas of the world would hear about it. But more civilization is still needed in so many rural areas because the challenge they will have is the lack of internet facilities, while some don't even have electricity. It will take time, sponsors and several awarenesses for this to be achieved in full.
