The fact that Internet surveillance isn't totalitarian, however, doesn't mean that it does us no harm. We're watched so that we can be manipulated. Some of this manipulation is welcome. We might revel in algorithmic recommendation of music, we're pleased to be shown an advertisement for sneakers, we need computer help sifting through the mass of information. but there's another way to describe the convenience of the machine: It is the surrender of free will--algorithms make choices for us. This isn't so terrible, because our submission to manipulation is largely willing. Yet we rightly have a sense that we're surrendering far more than we intend and that we're being manipulated far more than we know.
