I agree the ideas of most today's products were created way back then. Yet, I don't think the technology was quite ready yet. 100 years after, we are finally there and making the imagination or the attempt to become reality.
Speaking of surprising technologies, we know frequency hopping was patented in 1942. The patent owners are Antheil and Hedy Kiesler Markey. Hedy Kiesier Markey was an actress. ;)
y_sasaki - "Ironically, those "miracle weapons" are put into action hoping to REDUCE casualities"
It's interesting to consider how many weapons have been thought to be so effective or horrible as to make war unthinkable, and prevent it from ever happening. Sadly, none have ever met that goal. I doubt that any ever will.
As long as we are primitive enough a species to think that violence, or the threat of violence is the path to peace, we won't have peace. Part of the problem is that everyone has to agree on peace to make it work. Only one has to agree on war to make it happen.
I wonder if we'll ever do the opposite and find a non-military technology to be so wonderful as to make war obsolete.
"Weapons of mass destruction" took action first time on WW1 (and sadly, not the last time). Tanks, Machine guns, Chemical weapon, Heavy atritalies, Air raid to civilian population... Ironically, those "miracle weapons" are put into action hoping to REDUCE casualities, to get decicive win in battle, shorten the war. We knew those assumptions were speculaculary wrong. And I think we should reminder that.
