It's true that freedom of speech comes at the price of people being able to spread misinformation and say hurtful things. But that is a fair trade off compared to the alternative which is allowing a group of people the ability to dictate what can and can't be said. That power when wielded in the wrong hands has proven time and and time again throughout history to lead to authoritarianism, tyranny and suffering far greater than anything free speech can enable. And I completely disagree with you that an AGI ruler will make this better as they will be subject to the same biases or worse, biases we don't understand. Not to mention that we are very very far away from AGI.

When it comes to disinformation, the best cure against that is education. It's time we as a society stop outsourcing our thinking to others. We must take the time to continue our learning every day, only then can we maintain freedom of speech and combat misinformation. Not by letting a group of elites decide what is the Truth™
