To be honest, I'm more worried about the lack of education we have these days. We seem to take for granted that a certain level of knowledge is unnecessary these days -- because we can just let the factories deal with it. How many people know how to make preserves? How many know how to make beer? How many know how to grow vegetables? How many know how to fillet a fish? It's just basic information that used to be common knowledge in every household -- it's already lost to the majority now. Of course we can relearn it from books, but I often think that together with this explosion of access to knowledge, we're already in a bit of a dark age. I suppose the cause is that most are uninterested. Even me, if I'm honest ;-)
