Yet Russo seems to suggest that there are really substantive differences between I1 and I2:
While Internet1 is open to pretty much anyone with a computer, access to Internet2 is limited to a select few, and its backbone is made up entirely of large-capacity fiber-optic cables. Rather than Internet1, which is cobbled together out of old telephone lines, Internet2 was built for speed—the roads are all wide and smooth, like your own private autobahn. Internet2 moves data at 10 gigabits per second and more, compared with the 4 or so megabits you'll get using a cable modem. As a result, Internet2 moves data 100 to 1,000 times faster than the old-fashioned Internet.
However, it seems reasonable to think that the demand for swifter connections and more broadband will increase exponentially in the next few years and the record thus far is that the Internet developers have responded to these challenges with creative gusto. We are creating a world wide neural network in which I2 is merely the advance harbinger of a cyber consciousness just now awakening to a new world.
