Even in the recent past, all the countries dominated by the Soviet Union have gone for a half of century without problems, while a supermajority of their citizens actively hated their government, and by "hate" I mean like really wishing all of them dead.

This was made possible with traditional surveillance.

With the modern surveillance means and with drones and robots, there will no longer exist any way in which even a great supermajority could remove a government.

Those countries were occupied by a foreign empire. You may recall what happened when they attempted regime change - the Soviets would roll in.

As soon as Gorbachev made it clear that he's not going to do that, all of the Warsaw pact states immediately overthrew their governments.

Thank you for providing an example that further supports my thesis. No government can survive very long when a supermajority of the country hates it.
