Nah. Technically a graphical interface is an interface that is facilitated through the use of graphics. Not all computer interfaces are graphical. Some interfaces are audio/voice (such as Alexa and Siri, Screen readers for the blind). Etc.

I think the point I was making is that “what is a GUI” is not objective. And its colloquial definition may also evolve over time. The fundamental question right now is, is text graphical? Some would say no. I’d say yes. What about code highlighting? Code hinting? The buttons on your text editor? aren’t those graphical? Of course they are. I’d argue that they are the best GUI for crafting custom computer instructions.
