Susan Blackmore: "Genes, memes, and now what?"

Susan Blackmore, author of the excellent book The Meme Machine, has suggested that beyond genes and memes, there is a new evolutionary "replicator" on the scene. She doesn't have a name for it, but it's related to the difference she sees between memes and digital information. From New Scientist:

Memes work differently from genes, and digital information works differently from memes, but some general principles apply to them all. The accelerating expansion, the increasing complexity, and the improving interconnectivity of all three are signs that the same fundamental design process is driving them all. Road networks look like vascular systems, and both look like computer networks, because interconnected systems outcompete isolated systems. The internet connects billions of computers in trillions of ways, just as a human brain connects billions of neurons in trillions of ways. Their uncanny resemblance is because they are doing a similar job.

So where do we go from here? We humans were vehicles for the first replicator and copying machinery for the second. What will we be for the third? For now we seem to have handed over most of the storage and copying duties to our new machines, but we still do much of the selection, which is why the web is so full of sex, drugs, food, music and entertainment. But the balance is shifting.
