Hmm. A lot to ponder. So, you're prophesying that future generations will be comfortable with non-tactile things, things that disappear with the click of a button. No paper trail, nothing to hold or keep. It's a tough future to grasp. I agree that land-lines are almost obsolete now that anyone can carry their communicators everywhere in the world. Television is slowly being superceded by the Internet. Sadly, the networks have cottoned on to this and are 'larding' their shows with a limited number of ads.
My mind is struggling with the concept of not really owning anything, because that's what the electronic age seems to be moving toward. You don't own mp3s or e-books that are stored on an electronic device. If the memory fails on the device, all your music and books disappear (unless you've backed them up on another device).
Being a conservationist, I'm inclined to think that some obsolescence is a good thing - newspapers create waste and cause trees to be cut down. Except for small town papers that cater to a limited audience, let the Times and the big publications go. Same for magazines - read them online, copy and paste what you want to save.
Also, Carlos, you can add to your list computer applications such as Word, Photoshop, etc. With the advent of 'cloud computing' we are being induced to use the internet for all our computing needs, for a price and not actually own the programs.
