The all powerful police state is coming, is already built up, and technology is just being connected to tie up loose ends. All those internet connections, cell phones towers etc will tie together in the largest organized survellience system the world has ever seen.
Everyone will be tracked and monitored all the time. Cell phones with microphones, cameras, motion sensors, thermometers, and tons of other sensors, vehicles with various communication technology and similar sensors, city cameras and permanent flying drones everywhere. All of these things are already being done in various portions of the nation.
AI will analyze everything done by everyone digitally, profiles will be created by AI, and intelligence agencies will review things and task out things to national and local law enforcement.
A lot of the attributes assigned to Germans were actually Prussian. The Prussians were quite honorable, but absolutely efficient and organized. What would eventually be the Gestapo and eyes and ears of the Nazis was first the Prussian Secret Police.
When the ends justify the means is quite interesting in the Soviet System. The Nazis get a lot of attention for the attrocities of Poland, but did you know the Soviets actually rounded up and killed off most people of Polish ancestry living in Russia before they invaded Poland, just because it was presumed they would have loyalties to Poland. They just went missing. They were arrested and executed in secret.
The Katyn Massacre gets some attention with the soviets killing most military and intelligence that were arrested or surrendered to the Soviets, one by one, as they thought they were just being interrogated. But a lot more actually happened:
Later the people that best resisted the Nazis in Poland or helped partizans or persecuted groups or were involved in other anti-nazi efforts were executed by the Soviets, because the Soviets figured if they were willing to work against the Nazis they posed a danger to the Soviets. Those willing to take up arms against government or support those that did were better off dead than even risking they do the same thing again.
Now the AI will flag you as better off imprisoned or dead for government interests. Who would have thought Terminator was on the right track and the machines would be the ones calling the shots.
