Self driving vehicles.
Algorithms to make planned journeys for everybody according to map history in a city, making it in sync with the train times.
No more waiting in lines, making it an option saves time for everybody, even the place to which you want to go.
Interactive appliances that assist and adjust themselves based on previous user settings and the environment. (Car AC, volume of a speaker, television programs you watch will be ready by the time you reach home, timed cooking based on your day to day habits, etc..)
Endless possibilities which will end only when we stop pursuing the idea more and more.
