I assume he wanted the readers to now think negatively about this future. I kind of like it. Plus, that's not just the "Google world". It's the Internet. Do you think you can just unplug from the Internet 10 years from now? Can you do it now? It's only going to get harder, especially for new generations that are born with it.
What does worry me about the future, is governments having total knowledge about every single person, no matter what they are doing, who they are, and what service they are using. Do you really think they will need Google for this? Sure, in a way companies like Facebook and Google are making their jobs a lot easier. But do you think this will matter when they will have quantum computers? They will be able to get signals from a billion actions you've done on the Internet, regardless of what service you used. Gmail and Facebook usage will just be some of the signals.
And what happens when governments have total knowledge about everyone, whether it's legal or not? What happens when the governments can predict with quantum computers the potential of committing every type of crime for every single person? Maybe you have a 0.0000001% to be a terrorist. Maybe a 1% chance to beat someone, and maybe a 5% chance to smoke pot. Do they arrest you now, or do they wait until the quantum computers predict it's 10%?
These discussions about privacy breaches from companies seem like mainly a distraction from the real issues to me. It reminds me of the outrage of gun owners who "want to defend against an oppressive government" and "protect the 2nd amendment", but don't make a sound when the government cancels the 4th, 5th or even the 1st amendment. Or the 6 months outrage of the media over Benghazi, while covering the AP spying story for like 3 days.
Google can't physically harm you or destroy your life. Governments can. I would worry more about that. A lot more.
