A touch of mental masturbation here. Say, WW2 never happened, Hitler died without rising beyond a paper hanger, genocide against the Jews never occurred, Japan never attacked anyone.
From WW2 we have the space programs, antibiotics, radar and then microwave ovens, dehydrated foods, several types of ATV’s, newer food preservation techniques, emergency medical techniques, synthetic oil, synthetic rubber, and more. As spin offs we have super strong plastics, computers, synthetic cloth, magnetic imaging, deep diving exploration subs, robots, television, Cablevision, compact tape recorders, to CDs. From WW2 we have the communications satellites invented by A. Clarke, scores of science fiction books which contributed to the development of space exploration, TV movies and various inventions.
WW2, believe it or not, benefited the world more than injured it, as awful as it is to say.
So, if WW2 had never happened, and with the bit of direct and indirect causes and effects I’ve given you from it, where do you think we would be today?
I think we would not have home computers, cell phones, communications satellites, the advanced cars we do have, computers in car engines, microchip answering machines, or even answering machines. Phones would probably still work on the old mechanical click and bang switches, there would be no optical fibers, no cable TV, no microwave ovens, no pen lasers and nothing like magnetic medical imaging.
We’d probably still be driving cars similar to the ones in the 60’s, perhaps a little better, but without the advanced plastic construction used today. TV would be free and transmitted via radio waves to antenna, like in the 60s, probably better, though, than what there was. We’d still be buying vinyl records played with a synthetic crystal needle. The great intercontinental airliners of today would probably be turboprops, much slower and carry less people because of no computers, no jet engines, no space age plastics, and no fiberglass. Fabrics might still be heavy and dull because synthetic fibers came out of WW2 which were later developed into lighter, more colorful fabrics.
We would not yet have been to the moon. We might just be experimenting with nuclear energy.
