Literally nothing that is taught in schools has any practical application in real life. LITERALLY NOTHING
There is absolutely no need for that. We communicate exclusively in emoji and videos. And videos captioned with emoji.
I don't see any emojis or video in your comment, Veho. I guess we still need the alphabet after all. Oh, and I also learned how to read and type in primary school - do you think reading and typing has no "practical application in real life"?
