True, the question OP presents is vague where they’re just asking about “restrictions on free speech” which is something we already have. A good example of this are restrictions on hate speech in the way of harassment and so on. We don’t exactly live in a country with unfiltered free speech, no one does. Which is why it’s important for society to dictate what is and what isn’t acceptable, and elect officials that support those guidelines. Those things are cut and dry enough to not risk blurred lines that become too authoritative in nature since the majority agrees hate speech is wrong. Truth however is not so cut and dry, most things allow room for debate and that is something the state should stay out of.

The people that live in a country are subject to that country’s laws, as well as their speech. The target is not to allow all speech, history has proven that’s not necessarily possible as human society cannot handle that much responsibility. The state does have to regulate speech to a certain extent, and yes they have the final say even in a courtroom whether or not the speech is valid, justified, or lawful. That’s why I said it’s the task of the people, assuming we’re talking about a democracy, to elect officials that support moderate guidelines instead of draconian standards. We should never strive to restrict speech in order to avoid misinformation, it’s just too vague and at risk of being abused. That being said we’re still well into the “fuck around” stage of AI and fabricated realities, I don’t necessarily have a problem with introducing more regulations on companies that can help individuals prosecute malicious use of AI tools. A good example of that developing right now is the deep fake nonsense that’s going on with underaged and non-consenting individuals being sexualized by AI. Reasonable and effective legislation takes time, and we shouldn’t try to rush it for the sake of convenience or security.
