Thus, I came to the conclusion that the designer of a new
system must not only be the implementer and first
large||scale user; the designer should also write the first
user manual.

The separation of any of these four components would have
hurt \TeX\ significantly. If I had not participated fully in
all these activities, literally hundreds of improvements
would never have been made, because I would never have
thought of them or perceived why they were important.

But a system cannot be successful if it is too strongly
influenced by a single person. Once the initial design is
complete and fairly robust, the real test begins as people
with many different viewpoints undertake their own
experiments.

Imagine that Cray computer decides to make a personal computer.  It has
a 150 MHz processor, 200 megabytes of RAM, 1500 megabytes of disk
storage, a screen resolution of 4096 x 4096 pixels, relies entirely on
voice recognition for input, fits in your shirt pocket and costs $300.
What's the first question that the computer community asks?

"Is it PC compatible?"
