Crazy technology

So today we found out that July 11th is the big day that the new iPhone comes out, for $199. And on my brother's blog i saw this link,an amazing advancement in technology. (Check out the video) I wonder what else is going to be invented in our lifetime? I used to think Dick Tracy's watch was cool because it was like a phone. I'm crossing my fingers that my "Michael J Fox dream" will come true and one day I can ride my own Hover Board.
