What is the problem of the current Internet structure? What shall the characteristics of the future Internet be like? In a book called Trillions, Peter Lucas introduced two important concepts about designing the next version of the Internet: fungible device and liquid information. What are they? Why will this design make the future Internet more open. Why that version of Internet will give opportunities to more smart and powerful products? After reading the book, I made this mini documentary to explain his concepts, and give a hint of where we are now.
