"Desire Line" was originally an architect's term for paths made by people when walking across open grassland, what these lines represent are the shortest or most easily navigated routes between an origin and destination. The film uses this idea in the context of how an artificial intelligence might work: the AI generates optimal solutions to user problems as a form of desire line calculation. The film aims to interrogate the increasingly controversial role of Artificial Intelligence by visualising a statement from a bot about its experience on a Valentine's Day in the near future.
