in the next 75 years.....?

Question

in the next 75 years will the super high tech future really come??
i mean like moving sidewalks, flying cars, living on the moon or farther, super virtual reality, robots that do everything and cars the drive them selves, almost like star wars.
if not what kind of future will we be living in?

Answer 1

the super high tech future will likely never get here. some ( a very few) of the facets will, but probably they will be owned /operated by the wealthy. the rest of the world will have cheap knock offs or deal in the used/ refurbished hand me downs of the wealthy.
Have you seen Bladerunner? watch it with an eye not for the tech, but for the separation of classes.
another good one would be Johnny Mnemonic. And AI was a good movie right up until the boy was woken in the future. It would have been a better movie with the anguish of his 'death' in the ice.
There may be some living on the moon. but I expect in 75 years it will still only be comparable to living in Antarctica today.
moving sidewalks is unlikely except in some restrictive planned community. that is a luxury that does not generate any revenue. So the only ones that will pay to put it in will be planned complexes that are trying to show off their exclusivity.
flying cars are likely. the population growth is causing urban congestion. those that can afford it will pay for such a luxury.
Virtual reality... maybe. certainly if science can make the human-machine interface happen someone will be willing to pay for it. I don't think it will be perfect enough to do a direct brain interface within 75 years though. Prosthetics and cybernetics yes, but full sensory duplication is a massive amount of data.
