Spidey said: The one with peoples brains hooked up to a machine can loosely be considered predicting the internet. I think as long as you have the right idea you've done a good job. Impossible to draw an accurate detailed pic of 100 years into the future, but getting the themes and ideas can be done. One thing nobody predicted is the massive rise of cell phones to the point where everyone has one and is constantly wearing it to do EVERYTHING for them. But people did predict we'd use a computer chip on our brain on us to do everything for us, and that's kind of close.
