Definitely mind blowing. In the wrong hands, the magic bullets and the robot gun are a bit worrisome. The hoverbike, and the augmented reality eyeware are just really cool. The brain-computer interface seems like it has amazing potential for both good and harm. I certainly like the idea of curing Parkinson's disease, but as it becomes more powerful and communications flow in both directions, the potential for abuse must also be considered.

I guess there's a reason why we have a millenia-old cliche about the double-edged sword.
