During the great manure crisis of 1894 in which horses population exploded in New York city as they where a means of transportation the Times of London estimated that by 1950 every street in the city would be covered by horse manure. A prognosticator also determined that by 1930 horse droppings would rise to Manhattans third story windows.
But there was something unaccounted for which couldn't rationally be conceptualized by the average person at the time, the creation of the automobile.
I do not remember exactly where I heard this certain bit of information but someone hypothesized that if people brought horses into the city in an aid to
move out of the city roads would be blocked by manure.
I feel your question will receive answers much like the one above rather than someone actually stating that "cars will change how we travel and end the issues which we currently face with horses"
If the average person could predict the future with such ease many would be rich.
Its extremely hard to bet on future technologies as your not in the "future" (or present if you want to think about it like that LOL) yet and cant account for all the things you will know during 2017
But my overtly optimistic and currently ignorant answer to your question is Bitcoin.
