Fiber-optic communications. First of all, that it
became a medium for communications at all. Second, the
huge increase in the amount of data carried by a single
fiber—and how beautifully and with how little loss. It
replaced microwave links and all this other crazy stuff
and drove the cost of communications so low that
everyone could go around running fiber—and,
unfortunately, they did.
"In the past, in many industries, much of the economic
value chain—the ultimate price paid for a product—was
shared with all the intermediaries, like stores and
distributors. Moving things online as quickly as is
practical shortens this chain. Cisco, for example, does
billions of dollars of business with no salesperson
involved. The customer places the order and the computer
causes the device to be built, or at least extracted
from the warehouse and shipped. It's not just about
distribution but also about eliminating intermediaries.
It's about the wave of changes that occur when methods
based on old technologies don't work in the modern world.
"It's now very easy to do things that were once hard.
Take stealing text. In the past, you could get a copy of
a textbook out of the library and photocopy every page.
Now, copying it online is easy, and it's free, so
everyone does it. It's not that more people have become
wicked; it's just that theft has gotten easier."
