"I, Robot" with Will Smith was just on TV. It was a much better movie than I had thought. I thought it had a simplistic view on the three laws of robotics, but it really didn't.
Let's consider two worlds:
1) Our present world. We are free, but but war and crime and illness are rampant.
2) A world where Artificial Intelligence and robots have cured illness, and are stopping anything, including other humans, from hurting any human. You can live 300 years and you never have to fear violence or accidents, but you cannot hurt another, and if you are in harm's way, robots will block you. Let's postulate that you *are* allowed to hurt or kill yourself, just not others.
Which world would you prefer?
