Every time I attend an educational ICT conference, at least one of the speakers talks about how little we know about the future. The refrain goes something like this:

1. Kids entering school now will be leaving to join the world of work in around 2030.
2. We can’t predict what the world is going to be like even in five years’ time, let alone 20.
3. Therefore we need to teach kids 21st century skills (working as part of a team etc).

This all sounds profound and straightforward, but it really isn’t.
