> I remember Slack eating up my CPU when it had to display several animanted emojis at once. I remember using phpBB back in the late 2000's, viewing a page that had at least 100 animated emoticons on it. It would slow IE6 down to a halt. But then I tried Chrome or Firefox (I forget which one) and it didn't even blink showing the same page. I even remember reading some developer posts about things like that at the time.
