Counter-argument - look at the rise of civilization. It depended on evolving from cave paintings to pictograms/hieroglyphics to alphabets. Relying on graphical icons is a regression. Textual written language is the most precise, expressive, and efficient way to communicate information.
It's a common misconception that a Graphical User Interface is necessarily more "picture based". It's not really. The main interaction of human to machine thru ANY computer is still always and primarily going to be TEXT.
We as a species are simply, vastly READING more and more than ever with the rise of computers. The idea that computers are "killing books" or literacy is IMHO a totally wrong concept.
The truth is we are ALL just READING and READING and READING more and more, the more time we spend using computing devices.
Yes, we're not actually reading "a book" so much any more, since there's no need to limit exposure to text printed on paper bound by leather, LOL.
Case in point? The number of browser tabs that I keep constantly open across three different browsers on three separate computers is clear testament to this fact, and I suspect the vast majority of people reading this "out there" are all in similar setup.
A GUI simply makes the formatting and presentation of all these words, words, words... so much better, and to include images too, and to enable different fonts and color and layout of the words for the user's easier consumption.
A CLI on the other hand that offers only white text on black screen and "one command at a time" can do a lot of the same things, sure, but MUCH LESS efficiently.
