If you define yourself by what you do, what you buy, who you know, where you go and what you do when you get there, then you’re standing naked by the freeway and everyone’s snapping pics as they whiz by.
Technology affords you two choices: make yourself transparent and reap the benefits of personalization, or disconnect and live off the grid. I honestly don’t see the in-between. Your data may not all be accessible, but it’s all out there. And it’s only a matter of time before systems get better at mining it all.
