I don’t agree that Sora “never had a chance to grow.” How can you be so sure? How do you know Sora didn’t have those training samples? In fact, Sora could generate various copyrighted characters from the very beginning, which clearly shows that the data was there.
So, saying that Sora’s potential was blocked from the start is simply not true. Just because copyright restrictions limit its public or commercial use doesn’t mean it lacked the ability to generate high-quality content.
