In the discussion around generative AI a lot of the debate has focused around this same binary - truth and falsehood. Many are worried that the ability of generative AI tools to produce images, audio, video, and text may be used, or is already being used, to produce lies. Fake images, fake video, fake audio. That these powerful AI systems are a means of obscuring the truth or outright lying. We need, then, to clarify just what a lie might be, and why there is something more worrying hiding in plain sight.
