Unfillable expectations
By Scott Bradner
Why do so many good
technical people prefer to plan based on
wishful thinking
rather than the facts?
The particular thing
that got me wondering about this was yet another
instance where some
people asserted that in the near future there was
going to be an
explosion of cheap Internet bandwidth for individual
users. They did not
quite repeat the claim that bandwidth was going to
be too cheap to
measure, a claim which is popular with some people,
but they were getting
close.
The identity of
these specific myth spreaders is unimportant only
because they are far
from alone in their beliefs.
It would be easy to
do a little checking and figure out how much
money the fiber
people, such as Qwest, MFS and Project Oxygen
(www.oxygen.org),
and the Internet service providers, such as MCI
Communications,
GTE/BBN and UUNET, plan to spend. But what I
can tell you is that
they plan to spend far in excess of the $3.3 billion
in annual revenue
generated by all ISPs in the U.S.
This would seem to
indicate that unless these companies are suddenly
about to become
somewhat more altruistic than their previous histories
would indicate,
cheap bandwidth is a pipe dream - an attractive one -
but a pipe dream
nonetheless.
But this is far from
the only example of this sort of reality disconnect.
A few years ago,
people were assuming ATM was going to replace all
other network
technology.
Even a bit of
thinking would have indicated that any wholesale
replacement of
network infrastructure with ATM was not in the cards.
There are just too
many alternatives and too much installed
technology.
Besides, the network
technologists were not about to stop thinking
when ATM was
designed - new technologies were bound to be
developed.
Today, we see a
reality disconnect in the belief by some that most
Internet users
already have some level of high-speed access. At least
that's my impression
judging by the amount of graphics that all too
many designers put
on their Web pages.
It's very broken
thinking to design Web pages that take many minutes
to download - with
much of that time taken in transferring complex
advertisements - and
expect Internet users will still be happy to deal
with you and come
back for more abuse.
What is it that
causes this type of inability or unwillingness to
recognize reality?
Clearly, some of the
problem comes from a need to attract venture
capital and sell
products. Clear, impressive stories are easier to sell
than ones with
qualifiers.
Part of the problem
also comes from the surface knowledge of the
issues that many
network managers and technology writers possess.
On the Web side,
showing your boss a Web page that is designed to
accommodate the
level of connectivity that real users have is not all
that rewarding an experience.
But the basic issue
may be just that complexity is a pain. It takes time
and makes people's
heads hurt to actually think through the
implications of
reality.
