A German chocolate factory predicted in the year 2000 we would have crazy things such as flying machines, more like wing-suits that jet-packs, consisting basically of wings, movable houses, flying machines that according to the drawing are small personal blimps, personal submarines, there is also one where the people are wearing balloons so that they could walk on water. Many other crazy things such as roofed cities, moving sidewalks, and weather changing machines. Another article states there will be robot barbers, flying firemen, deep sea divers... riding seahorses, big ones, opposite fishing, you are underwater, fishing for birds, fish races, something that looks like school mind control, and an underwater bus powered by a whale. Then another source says there will be voice/video calling, nailed it, a radium fireplace.
Almost all of these are good, happy hopeful things, a couple of the predictions were kind of close, but the only spot on one was really the voice/video calling, but some were close such as moving sidewalks, we have them, they just aren't common except in airports, and they predicted lots of flying, not really in the right way but flying was right. As for what are the most common predictions, flying and underwater things seemed very prominent.
I think in the future we will have holograms, and eventually personal jet-packs, I also think drones will play a large part in society as well as automated cars, I think we will have people on Mars, I'm sure there won't be like a civilization but yeah. I think virtual reality might be a good bit bigger part in entertainment. I also think China might start a war with the US.
I mean we have all the control over what comes around, fish aren't going to make the jet-packs, but I think we are going to make a lot of things animated, so we have control over what is invented, but we are making things we don't have to control because we are lazy. As for individuals we have less control because with all the automation of our lives. But I also don't know if there will be much more of a future for the human race at least, I think Yellowstone is going to explode and 99% of the worlds population will die. so yea, then either the human race will die out due to lack of food or disease or something might knock the human race out, but I think if at least 100,000 people survive then humanity might not die out completely, but I think due to everything shutting down the world will go into another ice age.
