Artificial intelligence raises new questions about purpose and scope of copyright

In the not-too-distant future, an AI system could generate works with very minimal human input at all. In particular, there is a requirement for a work to be "original" meaning "skill, labour or judgement" must be expended by the author. There are various interpretations of what this could involve. However, it is not clear how it applies to an AI system in practice and whether a machine could meet the test. Specifically, the author (being defined as the person by whom the arrangements necessary for the creation of the work are undertaken) is no longer responsible for creative input and so authorship and creativity must be separated out.
