Not going to happen, or if it does it won't last. The so-called sharing economy has mostly just devolved to low-barriers-to-entry entrepreneurship. AirBnB listings start off with ordinary joes renting out their spare bedrooms, but they got crowded out in a few years by businessmen providing real services, and consumers follow.

Uber drivers at first were mostly just driving in their spare time, but over the years the professionals came in and crowded them out.

The lesson here is that it takes work to provide a level of service that consumers are willing to pay for. That work is best done through organization and professionalization. Some guy renting his car out during the work day isn't going to find it profitable enough to continue doing when he has to compete against dedicated on-demand rental services.
