Storing swaths of data beyond the physical realm entails certain risks, like losing everything at the whim of an administrator's errant keystroke. Jen Wieczner is wary of cloud computing: "So entrusting my memories and records to Google and Facebook feels like plugging in, a Matrix-like oneness as though I have a USB port in my brain. It feels like a trust fall, or maybe riding in a self-driving car. I'm not the type of sharer whose every move you can track in Facebook status updates or tweets, but I do keep extensive personal annals, a sort of digital scrapbook of my own."
