I'm 48 years old, so I didn't grow up with them. I do think some of them have their place though, but there's quite a lot of novelty emojis. So I guess that I'm an old guy who only likes the old ascii emoticons.
Emojis are not stupid when used well. They help add more context to a text.
If people use emojis stupidly, chances are they'll use "the alphabet" stupidly as well if there were no emojis. As in "lol like wat de eff amirite anyway bei felicia!"
