I agree that this project emphasizes the unfortunate state of copyright. The last Civil War veteran died in the 1950s. Imagine he had written a memoir of his war experiences. If the United States had always had its current copyright laws, that book would only now be entering the public domain. Billie Eilish's music might not be public domain until 2150. There's no justification for such long copyrights. Artists aren't making art so their estates will make money fifty years after they're dead.
