The once-science-fiction notion of hyper-connectivity - where we are all constantly connected to social networks and other bubbling streams of digital data - has rapidly become a widespread reality.

With a fractured sense of self, we come to depend on what people feed back to us - often mediated through social networks - not what we are. We have complex identities but may become less able to act as a subject - confident in what we really are.

As the Internet of things advances, the very notion of a clear dividing line between reality and virtual reality becomes blurred, sometimes in creative ways.

There is incredible potential for digital technology in and beyond the classroom, but it is vital to rethink how learning is organised if we are to reap the rewards.

Predation is part of the everyday life of capitalism, in sectors as mainstream as pharmaceuticals, software and oil - where people's money, their data, their time and their attention are routinely taken in fundamentally asymmetrical exchanges.

It's the digital equivalent of the corkboard on the door. It's the idea that you're constantly connected even if you're not at your computer.
