Right, my point is that most CLI applications use text as output, versus most GUI applications do not.

Saying "Your point isn't true when there are exceptions" is a lazy argument, honestly. It is overwhelmingly the case that CLI applications use text as output, and my original point was specifically about how I wish this were more often the case with GUI applications — that you could somehow interface with them and compose them in the same way you generally can with CLI applications.
