I do not use emoji and I do not have (and do not want) colourful emoji on my computer (emoji as ordinary text characters would be acceptable for the purpose of displaying texts that have emoji, but I don't really need to that much, even if the texts have them, so I can do without that, too). The reason does not have to do with AI; I think that things can rarely be explained better with emoji, and is usually better to explain by text, and sometimes also diagrams will help (for computer programs, having good documentation is very helpful). (I also don't like Unicode.)
