Google’s Balloon Internet Experiment, One Year Later

> "The balloons are delivering 10x more bandwidth, 10x steer-ability, and are staying up 10x as long..."

I find the scale of these improvements simultaneously inspiring and troubling. What does it imply that you can make this sort of improvement in a year? It's inspiring because it suggests how brilliant these people are, and it showcases the power of human ingenuity, etc. It's troubling because it makes this improvement seem like low-hanging fruit. What other amazing things still are waiting to happen in relatively short time scales, simply because no one is thinking about them in the right way?
