Here's the math equation:
Facebook timeline + Dan Simmons Flashback + Stephenson's Diamond Age (Or A Young Girl's Primer) + AI = Possible future for us Gen Xers when we are old and in old age homes aka "TV" for the old people.
Here's the scene: you're old (but you don't have to be), you want to reminiscence, with/about your friends. Well, lucky you - you lived your life on Facebook (or Twitter or Google or your blog, etc.) and there is a ton of information about you to not only create your life timeline, but an avatar AI representation of you. (I've written about this in my scenario entitled, Trantor Mentors. Extra credit to anyone who gets the name inspiration.) So you can decide to jack in and re-experience certain times - or maybe just read your life like it was a book. (I admit I do that with my own blog sometimes. I am my primary reader, Oscar Wilde inspiration.) And there are different levels of media engagement. Like I mentioned, there's the book/reading, there's the watching, there's immersive VR (probably 3D).
Facebook might wanna consider teaming up with Singularity University right about now.
