Plus, what is bandwidth anyway? An Optical Carrier 768 line
carries almost 40 Gbit/s over a single optical fibre. If
one assumes that this can be driven by a single laser diode
of 1 W or so and that one pays $0.10/kWh, one gets a cost
of about $6.944 * 10^-19 per bit.
Granted, this is a ridiculous oversimplification, especially
since one has to throw in a few repeaters/routers in there
as well, plus all the encoding circuitry.
But I'm paying about $1.02 * 10^-11 per bit, retail.
Someone's making money. ;-)
