There are currently about 3.2 billion mobile subscribers in the world, and that number is expected to grow by at least a billion in the next few years. Today, mobile phones are more prevalent than cars (about 800 million registered vehicles in the world) and credit cards (only 1.4 billion of those). While it took 100 years for landline phones to spread to more than 80% of the countries in the world, their wireless descendants did it in 16. And fewer teens are wearing watches now because they use their phones to tell time instead (somewhere Chester Gould is wondering how he got it backwards). So it's safe to say that the mobile phone may be the most prolific consumer product ever invented.
Sensors everywhere: Your phone knows a lot about the world around you. If you take that intelligence and combine it in the cloud with that of every other phone, we have an incredible snapshot of what is going on in the world right now. Weather updates can be based on not hundreds of sensors, but hundreds of millions. Traffic reports can be based not on helicopters and road sensors, but on the density, speed, and direction of the phones (and people) stuck in the traffic jams.

This bloody sucks. I was watching Hitchcock's "What about Harry" and the little 6year old had the run of the town and surrounding woods. He went where he pleased. I don't think folks have gotten worse, we've just gotten scared.
