since IOT(internet of things) is on the process of being a part of our daily life, imagine all things being automated, cabs w/out drivers, high rise buildings with a robot assistant to welcome you a smokefree ride and maybe some old school bicycles for those that support environmental care but i would not remove beggars from the future city or include flying cars as it would not be practical putting in our world's gasoline reserves unless there would be a modern way of transportation that does not depend on gas, yeah there are electrically dependent mobiles but not that efficient to make an airplane fly or a ship move in water.

It's fascinating that most of the things we are discussing here are just a continuation of what we already have. We even think in terms of limitations we are familiar with. There actually already are electric planes. You're right, it is more challenging to make electric planes because of our limitations on battery technology, but if it's already possible, there's a good chance the technology will only make it more possible. Between 2015-2016 a solar powered plane circumnavigated the whole world! You can read about it here: https://en.wikipedia.org/wiki/Solar_Impulse. Maybe the future we be even cooler than we can imagine.
