In order to create the fastest
possible route between the human and the computer a fast conduit to every
function must be as accessible as possible on the screen: hence many
icons on many toolbars occupying much of the screen. The question is not
whether this works, it clearly doesn't. Users simply remember a few of
the icons that they use regularly and are effectively locked out of the
rest of the program.

"At every
screen are two powerful information-processing capabilities, human and
computer. Yet all communication between the two must pass through the
low-resolution, narrow-band video display terminal, which chokes off fast,
precise and complex communication"

In Taylorist design, the majority of Computer Human Interface as practised
today, the user or worker or soldier appears only as a subsystem whose
efficiency and therefore profitability can be increased by better designed
tools.
