The more technology advances, the more polluted the environment becomes, the more facile and incompetent man becomes, and the easier it gets for rulers to control societies.
Caligula, Qin Shi Huang, Imad ad-din Zengi, and the old tyrants could not even dream of exerting the level of control modern liberal-democratic governments exert over their citizenry.
With the advent of AI, automated police, and gunship platforms, it will become ever more easier for regimes to contain and crush all dissent.
I envision they'll roll out an AI-run crimenet system in the near future where cameras, facial and retinal scanners will scan everything in cities and suburbs and run them through a central AI.
Everyone will have a health chip implanted below the neck to track them and should you try to remove it without authorization, it will impart a fatal shock.
You won't take the chip? Fine, but without it, the banks won't let you access their service, and restaurants, delivery services, grocery shops, and hospitals won't let you in. They are private companies after all, and they don't do business with bigots.
The same will be true for other factors. Your attendance was missing at the local drag queen story hour? Well, your health chip has been automatically updated. You will be denied entry at the hospital next time because they are a private company and they don't do business with bigots.
The chip will also measure your bodily chemical composition and if your testosterone is too high, they'll schedule you for an estrogen shot. High levels of testosterone has been found by experts to lead to inequal, territorial behavior and is not conducive to an equal, tolearnt society.
All transactions will be digital and at any moment, the banks could cut you off from the network and legally starve you. Your Tesla hack car could be tracked and shut down any moment and can be commanded to drive itself to the therapy clinic where you'll be given mind altering drugs to make you more tolerant and anti racist.
Spores could be released into the atmosphere that automatically renders all humans sterile. In order to reproduce, you will have to go to clinics, where they will take your sperm and eggs and grow them in a test tube. In order to ensure an equitable anti racist society, they'll be engineered at the germline to ensure that they have complete tolerance towards pedophilic molestation, trannies, and black savagery.
