What questions aren’t we asking?

Over at Fururamb Martin posted this quote by Kevin Kelly:

Machines are for answers; humans are for questions. The world that Google is constructing — a world of cheap and free answers — having answers is not going to be very significant or important. Having a really great question will be where all the value is.

Asking the right questions has almost always been more relevant than the actual answers. But I really like the way this quote puts it in context of the internet age. What questions aren’t we asking? And how much of the Internet is not being indexed and returned in our searches?
