How much we really rely on tech.. and what happens when it fails - Virgin -

There are frazzled parents at the limits of their patience, looking after bored kids giddy at being on their school holidays but frustrated at having nothing to do. Passengers milling around, trying to nap on a hard floor, anxious that the next announcement on the public address system will be the one that cancels their flight.

And all because of a computer problem.
It’s the second edge of the sword of connected technology: systems that make aspects of life easier, cheaper, faster and more convenient – until they run into a problem.

If a system crash that affects one airline can result in this kind of chaos, consider the chaos if something bigger failed, like Centrelink, or a bank.
