Also, it's important to realize what technology is "indispensable" and what technology is not. If all of the iPads vanished tomorrow, or even the Internet, people would basically be OK. If the electricity went out across the country and wasn't coming back, it would basically be the end of our civilization. In fact, the "indispensable" technologies are so refined that people take them for granted, but their existence is much more amazing than that of the iPad. Being able to flip a handle in your own house and get life's most essential substance, ready-to-drink? Being able to get inside a metal tube and go clean across the country for a few hundred dollars? Being able to have your own vehicle that can go 80 miles per hour with refueling stations all over the country? Absolutely unbelievable.
