If I look at how the law is written, I get an impression that technically you might even say that copyright law doesn't exclude non-human authored works - they fit the clause of types of protected work, a machine might be considered an author, etc, HOWEVER, when all that is said and done, a machine can't have any rights or standing in court; i.e. even if someone would assert that a machine is the author of some work and has an exclusive right to reproduce it, then that right is unenforceable because the human society and its courts simply will ignore any violations of a machine's rights.
