I think there is a bit of confusion as to what defines the "Information
Super Highway" and the Internet.  The Internet, in my opinion, is not the
Information Super Highway (ISH).  I think people believe that the Internet
is the model for the ISH, it isn't.  The future is in broadband
technologies.  ATM today is asychronous (one at a time) (the Internet is
also asychonous only much much slower) and is not really isochronous (many
at a time) that will come about with BISDN Broadband Integrated Services
Digital Network, (FDDI II used isochronous channels in a token ring
fashion, but it isn't a popular standard) - Broadband ATM will be
isochronous.  With fiber optics, information gets transmitted at the speed
of light - basically like turning on and off a light switch -  binary on
0's off 1's.  It is very fast, but limited on the ability of the hardware
assimilate the transmission.  SONET (Synchronous Optical Network) was
developed as high-end transport technology for protocols like ATM to allow
multiple simultaneous transmissions over fiber optics.  The future will get
only more integrated with fiber optics media.  Right now a fiber connection
uses only one band of light. Future BISDN - Broadband ATM will use the
light color spectrum to send parallel information on multiple lightwave
frequency's simultaneously.  Bandwidth can only get cheaper and is a
commodity - the Telcos know this and is why they are going up the
technological food chain to the information sources.

The issue is that the Internet will be just another channel on a 500 plus
basic user connection.  TV cable, phone cable, radio, satilite will
eventually converge.  Whether fiber or satilite is a matter of opinion.  I
believe fiber will still be the predominant transport technology of the
future.  What is of concern to me,  is that just like Public Television or
Public Radio has a channel on the TV/radio frequency band, the Internet
will evolve into another channel.  I believe the Internet should be a model
for public communications, if doesn't get drowned in commercialism.  When
you look at the future of total information connectivity, it may be that
less than 10% (maybe less) of the future population will have an Internet
connection as we know it today, and the rest of us just subscribes to the
machine.  I also think just like Public Television, if something isn't done
publically, will require public financing of the Internet to maintain a
channel on the spectrum.  History is a great teacher, if we only listen.
