Several of Orwells novels were telling us where our political world was headed way before his time at the end of the second world war and we seem to be heading there even faster today....! If you get a chance Julia read it and his novel titled 1984 IF you want to see where our world is headed!
The descriptions of Winston Smith's living quarters, smell of cabbage, food rationing, "Victory" products like gin (or, with the allies, "Victory gardens"), careful rewriting of history, adulation of wartime political leadership (Churchill, FDR, Stalin, DeGaul), hatred of enemies, fear of spies, counter-espionage, bombed areas, and much else, were a clear description of the London of ... 1948! 48, 84. In a way, Orwell was extending the worst aspects of a war society into a future society in which those aspects, under the excuse of war necessities, have grown almost to perfection.
There are lots of dystopian authors who understood the nature of humans, orders of societies, the hunger for power, and the desire to have others controlled. That was the type of sci fi I've read tons of. What's happening these days is kind of familiar to me for having read so many of their writings. Orwell and others were insightful. I don't know if that makes them prophets.
I don't know much about the writings of George Orwell, but I'm sure H. G. Wells was a prophet. In 1913-1914 H. G. Wells wrote a book called "A World Set Free" in which he wrote about atomic bombs. Mind you, that was 26 years before the 1st atomic bomb was created by the Manhatten Project. And it was not until 1938 that German chemists first caused nuclear fission. in their lab. How Wells ever came up with the idea of nuclear bombs is a big mystery.
