9+ things that will disappear in our lifetime

Doug Johnson of The Blue Skunk Blog re-posted this list from Plinio Granado of 9+ things that will disappear in our lifetime and blogged about them here. Here they are: post office, cheque, newspaper, book, landline telephone, music, hard-wired computer gear, television, privacy. Privacy! But if we think about it, we are already losing our privacy in some sense when we do so much online. I was surprised that music was on the list. How will music evolve? It is obvious that many of the things on this list are already on their way out.

There was some good discussion about what would disappear. Also included in the article is a list of things that will disappear from education. Doug Johnson mentions classes organized according to age groupings. I know that this is supposed to be the way of 21st Century Learning, but I can't see how realistic that would be. I picture 5 year olds in the same class as 11 year olds. How could that work? What would that be like for the students' self-esteem?
