Takeway: try to recognize a potentially not profitable grinding operation by power centers. Try not to become a bag hodler :) Ultimately humans can say NO, no matter the power of the manipulation and coercion by power centers.
Fascists were temporarily embarrassed by Hitlers loss in Europe. But they're more or less back in power in America with the people behind trump that runs the show, the heritage foundation. As with Hitler they've joined forces with the billionaires.
It would be a mistake to associate either just with wealth and tax brackets.
Those kinds of documentaries muddle the water by being too conspiratorial and not building an idea of things that actually happened in context instead they're just raising the spectre of one cabal or another. They just make you afraid and say whacko things which is counterproductive to actually recognizing and forming actual resistance to real threats like present day reality show themed fascism by insecure idiots in power. (it was a much scarier time when the fascists were competent)
I doubt that if you took the smartest people today and equipped them with the knowledge and resources around at the time - and no more than that, so no modern insights or historical knowledge - they'd be able to do what Turing, Flowers, and the others did.
Reverse engineering and breaking an encryption protocol by hand and then mechanising it with just math and valve technology was an astounding achievement.
The world was arguably also less complex back then, so there was plenty of low-hanging fruit to snatch in terms of information theory
Don't let the Hideo Kojima's of the world fool you into believing they did everything themselves. It's an effort of many, many who do it for the love of the craft and are content to receive no praise for it
You can usually make the argument that any particular scientific or engineering revolution would have happened anyway with different people nor more than 25 years or so later, at least any advancement since the mid 19th century.
Sure but the rhetoric of hate and disastrously racist things were happening well before the war took place and soon after the party took power. It wasn't some mystery that these were terrible people, the extent of awareness of what they were capable of just got gradually worse. In an age of bigotry they were still extreme but not THAT extreme if that makes sense so some people were overlooking their words and actions in order to praise the return to prosperity. But anybody with good sense and a decent disposition knew very early on that these were bad people and not a desirable change.
I don't know how you'd go further in terms of "what it means" in any deeper sense. Trump praises Netanyahu and Putin. It's all just there on the surface. It's just the world we live in.
Hitler himself was not blond or blue eyed. So .. inferiority complex is a dangerous thing.
As for everything was a conspiracy .. I advise to read a bit more about that time. The german rich elite also thought they could control hitler and use him against the communists.
