Memes won't ever go away; if you're talking about the real meaning of the word that is - "an idea, behavior or style that spreads from person to person within a culture."
Exactly. That's like wishing war would go away. Like most other things, memes are not new. The ancient Greeks, for example, had a whole set of their own memes preserved in text that we lack cultural context to understand. One more well-known example is their (tongue-in-cheek) saying that all Cretans are liars.
I love memes, but then I also have a special fondness for pop culture callbacks and reflexiveness. So memes are like catnip to me. Though I'm not a purist by any means. I'm always annoyed at people who rag on other people for using memes 'incorrectly'. Yeah, sorry, I missed the memo where "I can haz cheeseburger" is 'correct' sentence construction.
