I think such articles underestimate the ingenuity and detailing that goes into inventions. The idea represented by the science fiction and its execution by science are not the same thing. Case in Point: The dream of human flight must have existed ever since man first looked up at the sky and found it beyond his reach. But to say ancient humans came up with the idea and Da Vinci executed it (unsuccessfully) would be either belittling Da Vinci's designs or the thought and imagination that went into them. Better to say ancients had some idea (Hindus with flying chariots, Greeks with wings stuck-on with wax etc.), Da vinci had some other idea, and Wright Brothers an altogether different one.
