Emoji is, today, incontrovertibly the world’s first truly universal form of communication. Another measure for assessing the uptake of Emoji comes from its penetration in social media applications. Some argue that Emoji is a step backwards to the dark ages of illiteracy, making us poorer communicators. But this view is nothing more than ill-informed and blinkered cultural elitism.
This is an excerpt from a study that is currently under review. I hope it can be of relevance:
It appears that the claim that English is losing its position as the number one global language is closer than we expect and it is not losing it to Chinese. Using pictures as a mode of communication is common in the analysis of early human development. However, the problem arises with the reading of history that promotes moving from pictures to writing as a mark of progress of the humanity. Professor John Sutherland from University College, London, evokes "caveman" mode of expression through pictographic form (Emojis blamed as words lose out to pictures 2015). Perhaps the dreariness of this situation of human regression into "cavemen" wall pictures can improve by Anthony Scaramucci's analogy of hieroglyphs to describe exclamation marks and "smiley faces." An ancient Egyptian civilization may have much more positive connotations!
