Sure, but that's besides the point. It's sort of like that meme about "The World If <my pet policy was implemented>" (example: https://i.kym-cdn.com/photos/images/original/001/394/070/7f2...). It features over the top flying cars and infrastructure because it's trying to make a point.

When one says "we could have had flying cars, but instead we got X", that's the underlying concept. Whether or not the flying car is "practical" is kind of besides the point. Either that, or we need to find some other generally agreed upon term to represent an actually practical but futuristic invention that represents human progress (or the lack thereof).
