Robotics and AI have the ability to transform a great deal. We have still not fully explored Crispr and what's possible with biotech. AR & VR I think, once they reach maturity, will also transform society. Finally, I do think cryptocurrency will change as much about society as double entry bookkeeping did in the 14th century. This change may not be as radical for 1st world countries, but I think it will allow many developing countries to catch up much more rapidly.
