Our culture has brought forth all of these fancy new communications technologies. If there are some facts I need to know, I can probably look them up on my mobile phone. If there's some simple-if-you-know-it skill, I can probably learn it, too. I can learn things "just in time." I can forget them afterwards, too—I don't need to take the trouble to learn them well to memorize, internalize them. (Though if I need to do the same things over and over again, I probably will end up truly learning them.)
Our new just-in-time learning is changing our culture. It's expected that you'll keep learning throughout your life. If you don't, you'll be left behind. The world changes, and you must adjust. The world has always changed, but culture changed only as fast as people could learn about the changes. But now we can learn faster, and our culture changes faster than ever.
