The current state of my digital text is that of a two step system, a request is sent and out pops the response: a driver. I think in regards to the future, my application will stay fairly the same. The limitations are also miniscule in that there are no problems other than maybe in more isolated areas where the service may be a bit lagged.
I predict these factors due to the fact that enhancements can only go so far and the simple nature of the application leaves it to be already at a perfect level of complexity. You need a ride, it gives you a ride, time cannot alter this simple want.
