Emojis are not quite the same thing as picture writing (icons).

I used emojis for a while, then got kinda sick of them.

> a pure alphabetic script does not do a good job expressing emotions

Instead of a smiley emoji, I'll write "haha". Instead of a barf emoji, I write "barf". English has a million words in it. I'm sure you can find a variety of words that express emotions just fine.

?! being a form of picture writing? I don't see it.
