I think of this as analogous to the way computers have increased productivity at work. It's not necessarily that you get your work done faster, it's that you can have a better product in the same amount of time. So instead of wondering about the stuff that's easy to look up, wonder about deeper things. I love Tom Waits, but he's off the mark here: like so many other things, a "deficit of wonder" is a social problem, not a technological one.
