What will replace the internet?

What will replace the internet? I mean how is the internet going to be replaced? I was reading yahoo's feature article about the internet blackout when I learned through one of the links about the Japanese plan to replace the internet. Japan's minister of communications Yoshihide Suga has even talked about making this internet replacement technology available by 2020.

By then, I might no longer be chatting with my friends via IM but am I supposed to expect connecting with people the "Star War's way"? By the way if my son Kulay will be reading this post by 2020 (that is 12 years from now), this entry is blogged using an internet broadband connection with approximately 500 kbps speed.
