The other possibility is automation on the service-provider end. Once you've broken a task down enough so that a person can do it by following instructions from a cell-phone, the next step is to automate those instructions entirely. We're seeing this already with Google's self-driving cars vs. Uber, and I wouldn't be surprised if with recent advances in robotics & hardware startups, we start seeing Rosie the Robot taking over for Homejoy and Drone Delivery replacing Instacart.
