Interesting Business Model of Lyft
Android wearable devices have not rolled out in mass yet, but already Lyft can be found in the "Apps for Android Wear" section, Lyft is an interesting concept. On the one hand, it can cause a loss in revenue to the cab firms that have quite a lot of capital invested and a loss in the number of jobs that the industry can sustain. However, on the other hand, it creates jobs, employs stationary capital (cars) to become productive and provides a cheaper ride to clients.
It will be interesting to see the long-term effects of such business models on the economy -- technology is making everything efficient.
