A key idea in cybernetics is the self-reproducing machine: a machine that can make a perfect copy of itself, and importantly, a copy whose copy can itself make a copy. And so on, ad infinitum. We are very familiar with self-reproduction in biology, since that magic trick is the fundamental act of life. Back in the 1950s, while John Von Neumann was helping to invent computers, he was also playing with the idea of artificial self-reproduction, since a computer seemed to have some elements of biology. He began by trying to figure out what the smallest possible self-reproducing machine could be. What was the tiniest man-made thing that could reproduce itself?<br>Recently biologists have begun to ask a similar question: what is the smallest living thing we can imagine? Out of this line of thinking, researchers on the origin of life have experimented with the smallest possible bits of self-reproducing RNA — which are much smaller than what we find in the wild on earth. Biologists have also constructed a synthetic living cell with fewer genes than any known natural cell.<br>Life’s solution to minimizing the self-reproduction cycle is to begin with an egg or seed. Compress the full body of an organism into the tiniest lossless version of itself, one that can later unfold into a body able to survive long enough to duplicate via another seed or egg. It is an ingenious solution. Rather than reproduce fully formed, each generation grows (regrows) to its full mature state, while the seed or egg stage carries different survival requirements. Seeds have their own benefits: in dormant mode, they can maintain continuity over very long gaps. Some seeds can remain viable for decades or a century.<br>I’ve been thinking of civilization as a life form — as a self-replicating structure. And I’ve been wondering: what is the smallest seed into which you could compress the “genes” of civilization, and have it unfold again, sufficiently that it could also make another copy of itself? That is, what is the smallest viable seed of civilization? It must be a seed able to grow to reproduction age and express itself as a full-fledged civilization long enough to have offspring itself.<br>We know that oak trees can be compressed into acorns, and whales into a fertilized zygote, so I think civilization can be compressed into a library of sorts — a library full of knowledge, and perhaps tools. Many libraries already contain a lot of what we know about our culture and technology, and in the history section even a little on how to recreate it. But a truly self-reproducing library would have explicit instruction in compression and self-reproduction.<br>It is important to realize that this seed library is not the universal library of everything we know. For that we could just copy everything ever recorded, 1:1. As far as we know, that would work. But it might be the size of the world.<br>What would be the smallest version of a self-reproducing civilization? This kernel of the technium would not contain a copy of everything we know. Rather, it contains relatively few bits which, when expanded, can recover all that we know. The smallest seed library most likely contains only information, because with the correct information, you can build any tool needed from that information.<br>The unpacking of a seed like this requires the right environment and the right time scale. In the whale’s case it needs a mommy whale; an oak needs a forest and soil. So the creature is not entirely compressed into the seed alone — it may require an ecosystem as well. But a seed is still a handy thing.<br>I also believe, though cannot prove, that there is more than one seed. There is likely more than one way to compress and encapsulate the complexity of the technium, just as there is more than one way to fold a protein. We can imagine all kinds of seeds — libraries — that could continue some aspect of civilization by being replanted, rediscovered, or simply renewed. Some may be bigger than others.<br>So what is the smallest library that could contain the essential bootstrapping notions and knowledge of civilization? The seed must work as a bootstrapping device. As it unpacks itself from the seed phase, early stages form the foundation for the following stages. The initial tools are used to understand the remaining instructions, which are used to create yet more tools and understanding. And so it goes.<br>In 02014, Alexander Rose, director of the Long Now Foundation, assembled one example of such a seed library. He gathered about 3,000 books selected to contain the information needed to “reboot” human civilization in theory. If civilization were set back significantly, what books would a small community need to reconstruct it? The collection spans practical domains (agriculture, engineering, medicine) as well as the core cultural and intellectual ideas ( literature, philosophy,...
