# Silicon Seed: the ideal version *What the project looks like with no budget limits. Physically honest, but unconstrained.* *uzinaduzina, October 2026, draft* --- ## The whole, in one image Picture an **orchard** rather than a vault. Seven seed sites, on different continents, in different geologies and under different political regimes. Each holds the same three things: a **hall of the genome** that anyone can enter, a row of **sleeping specimens** sealed one per year, and a **germination workshop** with long tables and good light. Once a year, on the same astronomical day, every site wakes up. In each one, ten people who have never built a computer (the youngest five years old, the oldest past seventy) receive only the genome and a week. By the end of the week a machine is running at every site, and every machine computes the same number. That number is engraved, and the year is closed. Do this for a thousand years, and there will be a thousand numbers in a row, each one proof that the seed germinated that year. --- ## 1. The genome, ideal ### 1.1. Three materials, three different deaths No material survives everything, but different materials die of different causes. The ideal genome exists in three, so that no single catastrophe kills all of them. | Material | Scale | Survives | Fails to | |---|---|---|---| | **Fired ceramic tablets** | Human scale, naked eye | Water, fire up to firing temperature, time | Breaking, if dropped | | **Engraved nickel or steel discs** | Microscopic text, Rosetta Disk style | Breakage, damp | Strong acids, very long corrosion | | **Laser-written quartz glass** | Very high density | Heat, water, electromagnetic fields | Requires a microscope and a decoding key, both provided in the ceramic layer | The ceramic layer is the **core** and never depends on the other two. The glass layer is the **library**: it can hold vastly more than the core, for those who manage to read it. ### 1.2. What it contains - **The core** (around 1,000 tablets): the whole path from counting on fingers to a working computer, at all four technological levels. Every concept is written on four levels of abstraction, from a five-year-old's version to the formal idea, and in three registers: image, number, text. - **The tools to read it**: a simple glass lens in every box, plus instructions for **making a lens from nothing**. Van Leeuwenhoek saw bacteria through a single tiny glass bead, magnifying around two hundred times, and a glass bead can be made in a flame. Even the microscopic layer is therefore within reach of a civilisation with fire and sand. - **The library** (in glass): the yearly rings and the layers of the decade, a history of computing told through its people, and each decade's state of the art. - **The map**: a tablet showing where all the other sites are. ### 1.3. Languages The text layer appears in the six official UN languages, plus Romanian, plus the language of every host site. The interpreters at each site renew it every year, noting which words have worn out. Over centuries the genome becomes a record of language change in its own right. --- ## 2. The machine, ideal ### 2.1. One architecture, four bodies The heart of the ideal version is a single instruction set built in four materials, with the **same program giving the same answer in every one**. Only the speed changes. | Level | Body | Indicative speed | Power | |---|---|---|---| | **Mechanical** | Levers, gears and marbles, driven by a falling weight that a person winds up, like the Clock of the Long Now | about one step per second | Human muscle, stored in a weight | | **Relay** | Electromechanical relays, hand-wound coils | tens of steps per second | Hand-cranked dynamo | | **Discrete transistor** | Hand-soldered transistors and diodes | hundreds of thousands of steps per second | Under one watt, so a person can crank it indefinitely | | **Integrated circuit** | Common logic chips or a microcontroller | millions of steps per second | Any small power source | **Ideal parameters of the architecture:** - 8-bit data, 16-bit addresses (up to 64 kilobytes of memory); - around 32 instructions, including conditional jumps, subroutines and input/output; - an instruction set chosen to be **explainable to a child at the first level**, not to be fast. The **conformance program** is a short calculation that every body must run and that must give the same number in each. It is the proof that the four bodies really are one machine. The yearly ritual turns on it (see section 5). ### 2.2. Memory that is woven In the ideal version, **both kinds of memory are woven**: - the **founding program** in core rope memory, as in Apollo: wire threaded through a ring means 1, around it means 0; - the **working memory** in magnetic core memory: small ferrite rings strung on a grid of wires. Magnetic cores keep their content **without power**, so a sleeping machine wakes up remembering what it last held. Both memories are made by weavers' hands and can be read by eye. ### 2.3. The machine diagnoses itself At start-up the machine tests each of its boards and shows, in lamps, which one has failed. Whoever finds it in a thousand years does not have to understand the whole machine to repair it, only the part the lamps point to. ### 2.4. Power without dependence - A **hand-crank dynamo with a flywheel**, sized so that a child can power the transistor version. - Terminals that accept **any direct current from about 3 to 30 volts**, through a regulator made of discrete parts and described in the genome. - **The mechanical body needs no electricity at all.** If electricity is lost as a technology, computation is not. ### 2.5. The seed writes the seed In the ideal version, the machine's output is not a screen but a **stylus that engraves soft clay**. A working machine can therefore write new genome tablets, which a potter then fires. This closes a loop that sat in the bibliography of the 2009 project from the start: von Neumann's theory of self-reproducing automata, and the 2010 keyword "human-aided machine replicator". The machine cannot build itself, but it can **write the instructions for itself**, and people supply the hands. The seed writes the seed. ### 2.6. Two seeds can talk Any two machines can be linked through the simplest channels there are, each described on a tablet: - a pair of wires and a slow serial protocol; - **light**: one machine's lamp facing the other's light sensor; - **sound**: tones through the air. The original concept wanted cable and wireless connections. The ideal version keeps the wish but uses channels that will not become obsolete: a wire, light and sound. ### 2.7. Two sizes - **The sleeping specimen**: the size of a shoebox, sealed, one per year. - **The open seed**: one large mechanical machine per site, in a public space, slow and visible, that visitors can run themselves. This is the monument. It exists so that the idea is *seen*, not just stored. --- ## 3. The sleeping specimens, ideal - **The capsule**: a hermetic glass-to-metal or ceramic-to-metal enclosure, filled with argon, with a desiccant and an oxygen absorber inside. - **Sealed terminals**: the capsule has power and signal terminals passing through the seal, plus a window over the lamps. A sleeping specimen can therefore be **woken and tested every year without opening it**. The opening ladder (1, 2, 4, 8, 16, … years) is kept only for destructive inspection under the microscope. - **Witness samples**: next to each specimen, loose samples of every component type are sealed in the same capsule. They can be examined separately, without touching the machine. - **Climate**: constant temperature and humidity, darkness, no vibration. Salt mines are close to ideal. Over a century this produces something that exists nowhere else: a hundred specimens of the same machine, sealed one per year, with a continuous record of how each component ages. Over a thousand years it is the longest materials experiment ever run. --- ## 4. The orchard: the sites ### 4.1. Seven sites, seven kinds of shelter Different kinds of host fail for different reasons, so the ideal orchard mixes them: | Site type | Why | What threatens it | |---|---|---| | **A salt mine** (Romania) | Stable climate, geologically quiet | Tourism, abandonment of the mine | | **A national library** | Legal deposit, the longest-lived institutions | Budget cuts, war | | **A monastery** | Centuries of continuity, a culture of copying | Secularisation | | **A university** | Students, technical skill, rebuilding for its own sake | Changing priorities | | **A museum** | Public access, conservation skills | Curatorial fashion | | **A village**, kept by the community | The *clacă*: the seed belongs to the people who rebuild it | Depopulation | | **Off Earth** | A micro-copy of the genome on the Moon, beyond any terrestrial catastrophe. A lunar library has already been attempted | Being unreachable for a long time | ### 4.2. Each site points to the others Every genome contains the map of all seven sites. Losing one site is a wound, not a death: any surviving site can reseed the lost one. --- ## 5. The ritual, ideal ### 5.1. The date: an equinox The ideal date is **an equinox**, the day when day and night are equal. It needs no calendar, no institution and no particular language, because it can be found from the sky alone, with a stick and a shadow. It falls on the same day in both hemispheres. Of all possible dates, it is the one most likely to be recoverable in a thousand years. The genome teaches how to find it. ### 5.2. The germination week At each site, every year: 1. **Ten gardeners**: the youngest around five, the oldest past seventy, none trained in electronics. 2. **One week, the genome alone.** The previous year's gardeners may watch and answer questions, but not touch. 3. The machine is built, at whatever technological level the site chooses that year. 4. **The conformance program is run.** Every site, at every level, must obtain the same number: **the number of the year**. 5. The number is engraved on a small tablet and added to the site's row. Sites exchange their numbers by every available channel. If all match, the seed germinated everywhere. 6. The **ring of the year** is written, every correction to the genome is recorded, and a new specimen is sealed. ### 5.3. The journey Each year, one gardener from every site travels to another site for the following year's germination. This is the journeyman's tour, as in the French *compagnonnage*, which is on UNESCO's list of intangible heritage. Hands travel, the craft mixes, and no site drifts into its own dialect of the machine. ### 5.4. The story around it Each site develops its own **custom**: a counting rhyme in the local language that holds where the seed lies and how to start it, a feast on the night of the equinox, a small object every child of the cohort takes home. These are not decoration. They are the layer most likely to outlive every institution. --- ## 6. The thousand-year arc | Year | What happens | |---|---| | **1** | First germination at every site. The first number of the year. | | **10** | The first layer of the decade is condensed into ceramic. The first specimen is opened on the doubling ladder at age 8. | | **25** | The first gardeners who were children return as teachers. | | **50** | A gardener from the first cohort becomes a keeper. The founders are no longer needed. | | **100** | The genome is re-engraved on fresh material, in the same form. A century of ageing data is published. | | **250** | The technological levels are re-evaluated. Has a fifth level appeared? Has one disappeared? | | **500** | Half the arc. The languages of the text layer have probably changed beyond recognition, and the image and number layers carry the meaning. | | **1000** | A cohort with no living link to the founders rebuilds the machine from the genome and computes the number of the year. **This is the definition of success.** | --- ## 7. What the ideal version deliberately is not - **Not fast.** Speed is the first thing that becomes obsolete. - **Not secret.** A hidden seed survives only as long as the secret, and secrets do not last a thousand years. - **Not owned.** No person, company or state can switch it off. - **Not only a monument.** A monument without a ritual becomes a ruin. - **Not dependent on any living technology**: no internet, no cloud, no AI, no single company's components. Everything needed is described from first principles. - **Not finished.** It is designed to be corrected every year, for a thousand years.
