There is a striking parallel between the changes in human generations and the upcoming transformation of technology. Over the last two decades, we've seen the spread of information technology as early adopters wrestle with the discovery of what these tools could do for them. The next generation of technology will move from the age of discovery to the age of clarification. But far faster technologies are just over the horizon. But bandwidth is only part of the system.
Mobility is another key element.
There are also a number of new short-range wireless technologies in development for use in the home. Of course, not all users of these networks will be human consumers. As the first two decades of the next century progress, we will continue to see advances in the sophistication of user agents of all sorts and the hardware upon which the network is run. Of particular note is Sun's Jini project. Distributed systems will likely come to include a wide assortment of embedded processors, microchips inside everything.
