http://www.cs.utexas.edu/users/EWD/misc/vanVlissingenInterview.htmlAs to the programming products that are used by people, I hardly have
first hand experience, my impression is that an enormous amount of user
time is wasted figuring out what the system does and how to control it,
which is the consequence of two sorts of happenings. First of all that
the designers have failed to keep the interface of a system as simple as
possible—which is a challenge; but as soon as you realize that the main
challenge of computer science is how not to get lost in the
complexities of their own making, it is quite clear that this is a major
task.
