Margaret Boden, a researcher in cognitive science at the University of Sussex in the UK, has developed one of the most widely accepted definitions of creativity to date. She sees it as the ability to generate ideas that are new, valuable and surprising. Using this definition, the works produced by machines like Ai-Da could be considered creative, argue her creators. Whether or not an algorithm or a robot itself can be described as a creative entity, an ‘artist’ in its own right, like a human, remains up for debate, and this in part comes down to authorship.
