He has some interesting thoughts about how the Internet will be used in the future -- and what will be connected to it. It will not be restrained to just computers. I found Cert's comments about how mobile devices will interact with the Internet most interesting.
In the next decade, around 70% of the human population will have fixed or mobile access to the Internet at increasingly high speeds, up to gigabits per second. We can reliably expect that mobile devices will become a major component of the Internet, as will appliances and sensors of all kinds. Many of the things on the Internet, whether mobile or fixed, will know where they are, both geographically and logically. As you enter a hotel room, your mobile will be told its precise location, including room number. When you turn your laptop on, it will learn this information as well--either from the mobile or from the room itself. It will be normal for devices, when activated, to discover what other devices are in the neighborhood, so your mobile will discover that it has a high resolution display available in what was once called a television set. If you wish, your mobile will remember where you have been and will keep track of RFID-labeled objects such as your briefcase, car keys, and glasses. "Where are my glasses?" you will ask. "You were last within RFID reach of them while in the living room," your mobile or laptop will say.
RFID tags have some shrinking to do before they'll fit onto a set of keys or eyeglasses. There's also a lot more at play than just the Internet in this scenario. Wireless technologies, such as Bluetooth and GPS, will be required. The important aspect is that they will all interact to share and retrieve information seamlessly.
This already is beginning to happen today.
