I listened to the first five minutes, and it's pretty similar to Carlin's later work.
I'm not clutching my pearls about this any more than Steamboat Willie going into the public domain.
Intellectual property rights are silly, and protecting dead entertainers' legacies is a waste of time. If a Carlinbot makes a good joke, good for the Carlinbot. What I heard wasn't very impressive.
Excellent point.
