If we ever have an industrial revolution or massive productivity gains again it will most likely involve autonomous machines for things like farming, construction, delivery, transport, etc. All of these things depend on increases in power efficiency or performance. It is possible that we are one or two "doublings" away from achieving this in a mobile package and then suddenly moore's law stops.

For example Tesla is betting on conventional cameras and tries to overcome their shortcomings with computationally intensive machine vision. Tesla's custom chips allows them to have more processing power which means they can install more high resolution cameras and other sensors.
