I don't know how anyone who has done much automation could say such a
thing. Command lines and pipes offer an exponentially greater set of
possibilities than could ever be presented in a GUI.
I don't know about others, but I spent many years being pro-GUI. I led
the charge for getting software companies to port their applications to
Windows and use IDEs for development. It is only recently that I have
come to my senses.
I should have known better. Back in the 80s when I worked on tax
preparation software, the marketing department wanted a more demoable UI.
So we put a ton of time into creating an interface that looked like the
IRS forms, instead of the one we had where the user keyed in a code that
indicated what line on what form they wanted to input, followed by the
input itself. When we released this, the marketing department loved it,
our customers' higher-ups thought it was nice, but the actual input
operators hated it. They were evaluated on how much data they could
enter, not on their enjoyment of the task.
