“Uh huh. Google takes a similarly generous view of its own motives on the politically vexed issue of privacy. Mr. Schmidt says regulation is unnecessary because Google faces such strong incentives to treat its users right, since they will walk away the minute Google does anything with their personal information they find “creepy.”

Really? Some might be skeptical that a user with, say, a thousand photos on Picasa would find it so easy to walk away. Or a guy with 10 years of emails on Gmail. Or a small business owner who has come to rely on Google Docs as an alternative to Microsoft Office. Isn’t stickiness—even slightly extortionate stickiness—what these Google services aim for?

Mr. Schmidt is surely right, though, that the questions go far beyond Google. “I don’t believe society understands what happens when everything is available, knowable and recorded by everyone all the time,” he says. He predicts, apparently seriously, that every young person one day will be entitled automatically to change his or her name on reaching adulthood in order to disown youthful hijinks stored on their friends’ social media sites.”
