“You can imagine why Taylor Swift wouldn’t want … videos of her purporting to say things she doesn’t say,” Stanford Law School professor Mark Lemley said.

“A lot of the videos that people are going to generate of these cartoon characters are going to infringe copyright,” Mark Lemley, a professor at Stanford Law School, said in an interview. “OpenAI is opening itself up to quite a lot of copyright lawsuits by doing this.”

If a company loses control over what their copyrighted characters do and say in user-generated videos, it’s going to be a problem, Lemley said.

“You can imagine why Taylor Swift wouldn’t want — even if pornography is off the table — wouldn’t want videos of her purporting to say things she doesn’t say,” he said. “I think the same is going to be true of cartoon characters.”
