If you jumped in a time machine and went 20 years ahead, what would you find?Some people believe you'd see that Americans barely own any of the things we traditionally have called "ours" as a the result of the sharing economy. In this hypothetical future, autonomous fleets of electric cars will replace the need for garages, and you will no longer need to own tools for random fixes around the house because they'll be provided in a moment's notice by a drone.The goods and services a person needs will be secured because of access, not direct ownership.
