In a few decades we'll probably see emojis showing up in formal writing like textbooks, news articles, and scholarly journals. Our descendants will find it odd and quaint to read English texts without them.

No, they won't. Nobody will remember 10,000 emojis.

I used emojis for a while on phone texting. I eventually realized they were juvenile and stupid, and stopped.

Save the artwork for wonderful things like the illustrations in the Pooh books.
