Diane Ravitch says: "This is a very interesting and important graphic If you are concerned about data mining of your child or yourself -- you are right to be concerned. Our government and the corporate sector wants to know everything about us. They want to quantify our lives and use what they know to create Big Data.Big Data can be useful in tracking public health trends and needs, but it can be destructive in defining solely as our data. We are humans. We are not robots. Take a look at the graphic. We must protect our privacy, our individuality, our voice, our uniqueness as human beings."
