Having a 5-year-old son who's suddenly into science and technology has made me realize that Peter Thiel was onto something with his famous quote: "We wanted flying cars, instead we got 140 characters."
My son talks all the time about inventions he wants to build when he grows up. A time machine. A teleporter. A car that can fly and bypass traffic. A spherical shield made up of lasers.
