And one of the co-founders of OpenAI (Karpathy) also quite literally said "The killer app of LLMs is Scarlett Johansson." the day after the announcement.
He wouldn't be the only person to want Scarlett Johansson voice inside ChatGPT, I read several comments wanting that (I guess "Sky" voice doesn't sound so similar after all), btw Karpathy doesn't really work for OpenAI anymore.
