The author Douglas Adams spelt out three key responses that we all have to new inventions and new technologies. Ring any bells?

1) Everything that is already in the world when you are born is just normal

2) Anything that gets invented between then and before you turn 30 is incredibly exciting and creative, and with any luck you can make a career out of it

3) Anything that gets invented after you are 30 is against the natural order of things and the beginning of the end of civilization as we know it, until it has been around for about ten years, when it gradually turns out to be all right really.
