If it sounds nothing like her, and there was no intent to make it sound like her, why would he tweet "The killer app of LLMs is Scarlett Johansson"?
Many people made the comparison right after it was released https://x.com/search?q=scarjo%20until%3A2024-05-14&src=typed... and https://x.com/search?q=johansson%20until%3A2024-05-14&src=ty...
why be an apologist?
OpenAI was given an opportunity by Scarlett to prove that they did not intend to make it sound like her, and instead of responding their choice was to take down the voice. (yet another signal)
I think you'd have to be willfully ignorant to believe there wasn't some intent here.
Whether or not it's legal to copy someone's likeness in this fashion is another story.
