A new electronic toy comes to market, & is an instant rage. Predictor is "a small device, like a remote for opening your car door. Its only features are a button and a big green LED. The light flashes if you press the button. Specifically, the light flashes one second before you press the button."
Whatever you do trying to fool the device - waiting for light to come, doing it very quickly, whatever - you cannot beat it.
Isn't it a demonstration that there is no free will - everything is predetermined? What does this demonstration mean for society at large?
