Sigh, ACLU, is this really that high a priority in the list of rights we need to fight for right now? Really?
Also, am I missing something, or wouldn't these arguments fall apart under the lens of slander? If you make a sufficiently convincing AI replica that is indistinguishable from reality of someone's face and/or voice, and use it to say untrue things about them, how is that speech materially different from directly saying "So-and-so said x" when they didn't? Or worse, making videos of them doing something terrible, or out of character, or even mundane? If that is speech sufficient to be potentially covered by the first amendment, it is slander imo. Even parody has to be somewhat distinct from reality to not be slander/libel, why would this be different?
