Humans have used images in written communication for thousands of years, with the earliest forms of pictographs dating back to 3300-3200 BC.
Using pictures to express ideas in written communications is not a revolutionary, new idea. In fact, it dates back to the earliest languages. Emojis are therefore just the latest incarnation of this linguistic component.
Hieroglyphics is a written language, where letters are represented by images. Emoji is not a written language. The images in hieroglyphic language are therefore more akin to our alphabet(s).

[Rejecting P2] There is no connection between hieroglyphics and emojis. Hieroglyphics are legitimate characters that take the place of letters of the alphabet, which emojis are not.
