> then why does everyone sketch a picture when trying to convey an idea?
Does everyone do that? I think I very rarely do. When I need to convey an idea on a whiteboard, it's still almost completely text, with a few extra symbols like directional arrows that I think are still effectively just symbolic written language.
Literally the only time I can remember sketching a picture to convey an idea is while playing Pictionary. The entire premise of that game is that it is much more difficult to get someone to say a specific word by drawing a picture than by simply writing down the word.
