What an unforced error on OpenAI's part, but revelatory to all of us how their leaders actually see the world around them: either people whose likeness and style to copy like Johansson or chumps like the rest of us who would marvel at the regurgitated synthetic likeness.
And really, how much worse would the demo have been if they hadn't cloned Johansson's voice, and instead used another unknown voice? If it was similarly flirty, we'd have fallen for it anyways.
