The BBC has a piece today showing how the World of Always On could be invisible, worn instead of held.

We've already seen undershirts embedded with medical sensors. But Ian Pearson predicts we're going to move, over the next 10 years, to a world of devices imprinted on the skin.

But the real, unspoken story here is ubiquitous networking, which combined with wearable and printable intelligence make everything intelligent. That means everything can be our servant, but as BBC furturist Ian Pearson notes, it also means anything can be our master, if someone else takes control of the network we depend on, and the intelligence in the device we're using.

The vision of this story is the idea of cyborgs -- half man, half machine -- being more than science fiction. That's actually a more appealing fear than the one in the above paragraph.

But it's just as real.
