At the heart of Alex Garland's provocative movie Ex Machina, is the concept of the Turing Test and the notion that giving an emerging AI a gender identity is potentially the only way to pass it. It's a very bold concept but it's bolstered by the fact that nature hinges upon our biological imperatives driven by our respective sex. Set within a claustrophobic environment and laced with a more than a hint of Joseph Conrad's Heart of Darkness, Ex Machina is an intelligent and challenging science fiction movie that taps into several very topical themes.
