Ironically, this almost makes it more human.<p>It's a surprisingly common experience for music students to excitedly tell everyone they know about a new piece of music they've been composing, saying it is probably the best thing they've ever written, and then a friend or teacher has to say, "I don't know how to break it to you, but you've 'composed' the Xth movement of Beethoven's Yth symphony."<p>And sometimes they will say, "I have? I don't think I've ever heard Beethoven's Yth symphony." But of course they have, just without realizing it. It was in the background of some movie they watched or something like that.<p>Unlike humans, I don't think AIs have any belief about whether their work is original or not, but it's the same type of error. And with similar legal consequences: people have been sued for stealing a melody (presumably not always consciously). The difference with AIs is they can produce much more output than humans, and it's muddier what is actually doing the creating (AI authors? users?).
