How many times in your life have you needed to create a new a glyph? Would the added expressive power make up for the inconvenience of having to explain the meaning of the novel symbols?
Before you can evaluate if it’s convenient to communicate better with others, you need some room to explore if it helps better grab something by yourself.
Also sometime it’s nice to express something for your own private enjoyment. Maybe it can spit also to something useful for the rest of the world here and there. But making this "predicted usefulness for the common" a requirement is depriving humanity of all this intimate joys and everything that can emerge from it.
