The Future

What predictions about the future were people making 100 years ago? This website shows an article that talks about predictions for the year 2000 from a 19th century German Chocolate company. They predicted police with x-rays, flying machines (hang gliding kind of), movable houses, undersea ships (submarines), being able to walk on water, a city with a roof, theaters, moving sidewalks, and machines that can make the weather good. 
What predictions about the future were people making 50 years ago? This website shows prediction about the 21st century from 50 years ago. One of the predictions was that our space exploration program would be much more expansive than it actually is now. There were ideas that we would have "moon colonies" by now as well and we would be able to purchase lunar terrain. Another interesting thing I read was how they though we would have "glow panels" on our walls where we could basically just touch a big screen on our wall and change the color/design on of our walls. This website also talks about President Truman's prediction for the future, he didn't predict very materialistic things, instead he said that we would have obtained world peace by now.
Determine if the list is a “wish list” – as in, these are the things one might hope for in the future, or more a warning. I think that some of the predictions were things that people would have liked to happen, but not necessarily expected to happen, things such as being able to walk on water. But some of the predictions were very understandable predictions and thoughts, like the growth of our space exploration program, or world peace.
Which predictions seem to have come true? Which turned out to be bizarre, off-track, or still out of reach? Some of the predictions that came true were things like the underwater ships, flying machines, theaters, and moving sidewalks. Some of the more wild predictions were things like being able to walk on water, or being able to purchase lunar terrain. I think one of the bizarre but reasonable and understandable predictions at the same time was that we would have world peace by now, its understandable, but at the same time it seems like we will never obtain peace throughout the world.
Can you identify any trends or patterns in these predictions? What concerns or achievements do they seem focused on?  For example, do people in general seem to be anticipating a better world?
