Look around you -- here will do, in this room. All around us, still clumsily drifting about in its primeval soup of culture, is another replicator. Information that we copy from person to person, by imitation, by language, by talking, by telling stories, by wearing clothes, by doing things. This is information copied with variation and selection. This is design process going on. He wanted a name for the new replicator. So, he took the Greek word "mimeme," which means that which is imitated. Remember that, that's the core definition: that which is imitated. And abbreviated it to meme, just because it sounds good and made a good meme, an effective spreading meme. So that's how the idea came about. It's important to stick with that definition. Well, you sir, you've got those glasses hung around your neck in that particularly fetching way. I wonder whether you invented that idea for yourself, or copied it from someone else? If you copied it from someone else, it's a meme. And what about, oh, I can't see any interesting memes here. All right everyone, who's got some interesting memes for me? Oh, well, your earrings, I don't suppose you invented the idea of earrings. You probably went out and bought them. There are plenty more in the shops. That's something that's passed on from person to person. All the stories that we're telling -- well, of course, TED is a great meme-fest, masses of memes. There's one particular curious meme which I rather enjoy. And I'm glad to say, as I expected, I found it when I came here, and I'm sure all of you found it, too. You go to your nice, posh, international hotel somewhere, and you come in and you put down your clothes and you go to the bathroom, and what do you see? Audience: Bathroom soap. SB: Pardon? Audience: Soap. SB: Soap, yeah. What else do you see? Audience: (Inaudible) SB: Mmm mmm. Audience: Sink, toilet! SB: Sink, toilet, yes, these are all memes, they're all memes, but they're sort of useful ones, and then there's this one. (Laughter) What is this one doing? (Laughter) This has spread all over the world. It's not surprising that you all found it when you arrived in your bathrooms here. But I took this photograph in a toilet at the back of a tent in the eco-camp in the jungle in Assam. (Laughter) Who folded that thing up there, and why? (Laughter) Some people get carried away. (Laughter) Other people are just lazy and make mistakes. Some hotels exploit the opportunity to put even more memes with a little sticker. (Laughter) What is this all about? I suppose it's there to tell you that somebody's cleaned the place, and it's all lovely. And you know, actually, all it tells you is that another person has potentially spread germs from place to place. (Laughter) Now, why is this important? Why is this useful, or what does it tell us? It gives us a completely new view of human origins and what it means to be human, all conventional theories of cultural evolution, of the origin of humans, and what makes us so different from other species. All other theories explaining the big brain, and language, and tool use and all these things that make us unique, are based upon genes. Language must have been useful for the genes. Tool use must have enhanced our survival, mating and so on. It always comes back, as Richard Dawkins complained all that long time ago, it always comes back to genes. The point of memetics is to say, "Oh no, it doesn't." There are two replicators now on this planet. From the moment that our ancestors, perhaps two and a half million years ago or so, began imitating, there was a new copying process. Copying with variation and selection. A new replicator was let loose, and it could never be -- right from the start -- it could never be that human beings who let loose this new creature, could just copy the useful, beautiful, true things, and not copy the other things. While their brains were having an advantage from being able to copy -- lighting fires, keeping fires going, new techniques of hunting, these kinds of things -- inevitably they were also copying putting feathers in their hair, or wearing strange clothes, or painting their faces, or whatever. This is why, in "The Meme Machine," I called it memetic drive. As the memes evolve, as they inevitably must, they drive a bigger brain that is better at copying the memes that are doing the driving. This is why we've ended up with such peculiar brains, that we like religion, and music, and art. Language is a parasite that we've adapted to, not something that was there originally for our genes, on this view. And like most parasites, it can begin dangerous, but then it coevolves and adapts, and we end up with a symbiotic relationship with this new parasite. Let's call them techno-memes or temes. Because the processes are getting different. We began, perhaps 5,000 years ago, with writing. We put the storage of memes out there on a clay tablet, but in order to get true temes and true teme machines, you need to get the variation, the selection and the copying, all done outside of humans. And we're getting there. We're at this extraordinary point where we're nearly there, that there are machines like that. And indeed, in the short time I've already been at TED, I see we're even closer than I thought we were before. So actually, now the temes are forcing our brains to become more like teme machines. Our children are growing up very quickly learning to read, learning to use machinery. We're going to have all kinds of implants, drugs that force us to stay awake all the time. We'll think we're choosing these things, but the temes are making us do it. So, we're at this cusp now of having a third replicator on our planet. Now, what about what else is going on out there in the universe? Is there anyone else out there? People have been asking this question for a long time. We've been asking it here at TED already. In 1961, Frank Drake made his famous equation, but I think he concentrated on the wrong things. It's been very productive, that equation. He wanted to estimate N, the number of communicative civilizations out there in our galaxy, and he included in there the rate of star formation, the rate of planets, but crucially, intelligence. Well, we did pull through, and we adapted. But now, we're hitting, as I've just described, we're hitting the third replicator point. And this is even more dangerous -- well, it's dangerous again. Why? Because the temes are selfish replicators and they don't care about us, or our planet, or anything else. They're just information, why would they? They are using us to suck up the planet's resources to produce more computers, and more of all these amazing things we're hearing about here at TED. Don't think, "Oh, we created the Internet for our own benefit." That's how it seems to us. Think, temes spreading because they must. We are the old machines. Now, are we going to pull through? What's going to happen? What does it mean to pull through? Well, there are kind of two ways of pulling through. One that is obviously happening all around us now, is that the temes turn us into teme machines, with these implants, with the drugs, with us merging with the technology. And why would they do that? Because we are self-replicating. We have babies. We make new ones, and so it's convenient to piggyback on us, because we're not yet at the stage on this planet where the other option is viable. Although it's closer, I heard this morning, it's closer than I thought it was. Where the teme machines themselves will replicate themselves. That way, it wouldn't matter if the planet's climate was utterly destabilized, and it was no longer possible for humans to live here. Because those teme machines, they wouldn't need -- they're not squishy, wet, oxygen-breathing, warmth-requiring creatures. They could carry on without us.
