But the sector is changing; Uber and Airbnb are growing away from what made them sharing companies in the first place. Once Uber eliminates the need for its drivers by introducing self-driving technology, Wernberg said the company would cease to be a part of the sharing economy. Airbnb, meanwhile, is making what Hiscott called an "extremely smart" move by becoming an end-to-end travel platform. Not only does the firm now sell users local 'experiences' in addition to their purchase of accommodation, but it has also agreed to buy hotel booking site HotelTonight and take a stake in Indian hotel start-up OYO, diversifying the business away from room sharing.
