First the hardware war, then the OS war, followed by the browser war and search engine war, and now the mobile war and social network war. This won't be the last... or could it?

Will we be using Facebook daily 5 years from now? 10 years? 20?

Or is the next war in augmented reality, which Google has a head start? (but using which social network?)

Anyone have good links to futurist thinkers on these topics?
