Emoji isn't used to express complex arguments. It is most often used to express emotions in text. Because people are hardwired to recognize emotions in other people's faces an emjoi activates different parts of the brain than text expressing the same feeling. This can make a conversion using text more like a conversation face to face which is important for lots of casual conversion that now happens via the internet. Finally emoji is important for many young children in Japan and China, (I'm not an expert on this). The issue is learning all the characters needed to express yourself is pretty hard and takes years longer than learning the latin alphabet. Further learning how to input characters on a computer takes even longer. However kids still want to communicate with each other and as a result use a lot of emoji to speed up the process for them. For them emjoi is how they want to express themselves.
