Re: the anxiety of parents about the future: the people who best handle rapidly changing circumstances are the ones who are comfortable with ambiguity and uncertainty. I think it's far less important to teach young people specific skills in technology X, and far more important to teach them how to regulate their emotions, how to make plans and effectively execute on them, and how to be objective about their own strengths and weaknesses. Unfortunately, this doesn't seem to be something that a standard education focuses on, so whether or not you pick up these skills depends on whether your parents explicitly taught them to you or you happened to get lucky enough to develop them on your own.
One of my favorite quotes, from Stephenson's The Diamond Age:
"The difference between ignorant and educated people is that the latter know more facts. But that has nothing to do with whether they are stupid or intelligent. The difference between stupid and intelligent people—and this is true whether or not they are well-educated—is that intelligent people can handle subtlety. They are not baffled by ambiguous or even contradictory situations—in fact, they expect them and are apt to become suspicious when things seem overly straightforward."
