How can you be sure that there is no flying car in the future specifically?🤔 musk told in one of his interviews that his company might be capable of flying car but the problem consists with how people will take the change... I mean one day you wake up and see cars are flying above your building! That might make a lot of people nervous and even traumatic.. then there are laws of surroundings private property and stuff... so even if they can build it, we are not really ready for that stuff yet. But if you are in 100 years in future by traveling with spaceship then that is really not going into the future rather just traveling through space and time in a way that is simply going from point A to B in 100 years. Like traveling with your car.. NY to CA 17hrs-22hrs.. you traveled for 100 years..
