If there is tyranny, it's just that it always comes down to power in the end. Freedom and the rule of law work well because they have made it easier for a society to flourish over the long term, but if conditions change so can their effectiveness. I wouldn't be surprised if human rights disappear like a puff of smoke if the 99% lose their bargaining power because of automation.
Firstly, More free speech sometimes means more fake news. Creating and spreading false or biased news are so easy, as the society goes, the problem we deal become more and more complicate, if we cannot get the right info and we do not possess the right mind how come expect us to make a ration decision, we all know what happened to Galileo, can anyone say what they did to Galileo is undemocratic.
Secondly, the common crowd are not that care about the truth, i discussed with a few people lives in HK through the internet, they actually do not know anything about the extradition law, and they still went to the protest. This is why I do not believe in any form of direct democracy.
