The Matrix (1999): Why Keep Humans Alive?

Why do the machines keep humans alive in The Matrix (1999)? Neo discovers that his everyday life is a simulation. But could an ordinary life inside it be useful work for the machines? The Matrix is one of my all-time favourite films. I revisit Neo's awakening, the training programmes, Cypher's choice and the rescue of Morpheus, looking at how the film teaches us its rules before Neo starts breaking them. From Trinity's rooftop escape to the lobby fight and bullet time, the action is part of what makes those discoveries work. Along the way, I explore the idea that the machines could use human brains for computation. Neil Gaiman's Matrix story Goliath, Google's work with neuroscience collaborators, virtual fruit-fly models and DishBrain's living neurons offer different ways into that question. The brain-power explanation is a theory, and the experiments do not demonstrate a human mind living inside a simulation. If your mind were being used as a computer, would you necessarily know?
