Technology has indeed gone very far. The problem is that is going beyond what people are used to. Some people think that paper and pen or pencil is necessary in the world. There was a study that proved that with pen and paper the mind recorded better what it was doing than in the computer. On the other hand I think that using a technique like this one, it could be replaced. Also the contamination and destruction of fauna habitats could end. This new generation could be the ones that start this new life and older generations could learn.
