...Along with the efficiencies and clever new applications that Big Data has yielded come big concerns about privacy. As science historian George Dyson noted in a recent article published in Edge.org, "If Google has taught us anything, it is that if you simply capture enough links, over time, you can establish meaning, follow ideas, and reconstruct someone's thoughts. It is only a short step from suggesting what a target may be thinking now, to suggesting what that target may be thinking next."
...Here's an easy prediction: Big Data is only going to get bigger. Every year, more sensors will produce more signals that will be more quickly analyzed. This will lead to more convenience. And more concern. Mr. Dyson – whose physicist father, Freeman Dyson, grappled with wondrous but fraught technologies such as nuclear energy – sums up the Big Data revolution this way: "Yes, we need big data, and big algorithms – but beware."
