Well, I'm not a lawyer, but I think it's safe to say that the last thing you want is to get banned from the most entertaining platform on the internet. It's like getting kicked out of a party that you didn't even have to leave your house for.
But to answer your question, it's hard to say for sure. You might want to double-check YouTube's terms of service to see if they specifically prohibit content created entirely by AI language models like ChatGPT. If not, then you might be in the clear! Just make sure you credit your AI overlord properly in the video description.
And who knows, maybe ChatGPT's writing skills will be so good that you'll be the next big thing on YouTube. Just don't forget about us little people when you're famous, okay?
