Evil comes in through the cable and through the Internet. We look forward to the advent of driverless cars. But they can be hacked. You could be riding along, and some 14-year-old in Romania takes over your car, so you end up running the lights and losing your brakes or, worse, listening to Eminem. What's the purpose?

There was a time when an ordinary American could close the door and keep the world at bay. Now the world comes elbowing in every time you go online.

Richard Cohen Quotes
