In the so-called Internet of Things we're headed for, computers may be all-pervasive, wearable, embedded in everything, unobtrusive, practically indetectable and inescapable.
They are likely to be always communicating with the other computers all around them, and privacy will be a dream of the past.
Unfortunately, counter-surveillance technology does not appear to be keeping pace with surveillance technology, and since most people don't yet seem to care about being surveyed, there isn't much of a market for it.
On the other side, most companies (and their oh-so-helpful tech enablers) love to spy on their users, and see nothing wrong with doing so (or at least don't let any moral qualms stand in the way of a profit). So there is a lot of incentive for spying and little incentive for not spying.
Consciousness is slowly starting to emerge among the general population that this is happening, but there doesn't seem to be much of a backlash. Few are taking a stand.
