The answer is mind blowing. Watch the video in the link below. Thousands of high atmosphere solar powered drones - controlled by algorithms - will provide internet access to the half of the world currently without it. The planes are as large as Boeing 747 but weigh 160 kg. They can fly for 5 years without landing. And yes, because it's Google, they will be much more efficient tools to spy on all of us and eliminate all vestiges of personal privacy. But it's so damn cool and audacious I (almost) don't mind.
