Consider the saxophone. Someone invented that. Or some initial version. Then it was iterated by millions of people; further millions learnt to play it, millions wrote music for it, over thousands of years. Some people were very famously good at it. And now we have spent a trillion dollars so we can get a computer to play something that sounds like Charlie Parker. You could have listened to actual Charlie Parker recordings for almost nothing. Have we cured cancer yet? The fuck we have.
