The last few hundred years have seen dramatic advances in scientific and technological developments. Yet, when we imagine a future 30 plus years away, we tend to “see” scientific advances arriving prematurely. Folks in 1950 thought everyone would have flying cars by 2000, and, likewise, all diseases would be cured by then.
One area, however, where that movie’s predictions seemed pretty close was advances in graphic, visual technology and information transfer. (Though, they still didn’t predict Facebook, I don’t think.) That movie came out when 8 bit Nintendo was the current technology.
I think holograms aren’t too far off. But when are we going to get flying cars and Mr. Fusion? And cures for cancer? Perhaps we’ll have to wait till 2100.
