The Wrench, the Song, and the Skull on the Back of Your Head

John Barnes wrote a spy novel in which the spy's primary weapon is a lute. That alone would be worth marking. But *The Armies of Memory* — the fourth and final volume of the Giraut Leones sequence, published in 2006 — buries something stranger beneath its espionage plot: a sustained, uneasy argument that memory itself is the terrain over which every war is fought, and that the technologies we build to preserve it inevitably become the instruments of its destruction.

The psypyx is Barnes's central conceit, and it cuts deeper than most science-fictional immortality devices because it does not resolve the question of personhood — it sharpens it into a blade. A psypyx records a consciousness at the molecular level. It can be stored, copied, implanted in a host body, or subjected to "destructive deconstruction" — a process Reilis, the aintellect, describes to Giraut in terms designed to make him vomit: "If you can vividly imagine that thing they show in horror movies — a staked vampire burning down to a skeleton, then a skull, then teeth, then ashes, remaining fully conscious the whole time — then you have an inkling." Margaret, Giraut's ex-wife and spymaster, cheerfully explains that the pain of DD is only applied if the subject refuses to cooperate — otherwise it's "like having a perfectly healthy, pain-free body and going through a planned-and-directed Alzheimer's till there's no more you." This is presented as the merciful option. I have written about Bujold's *Mirror Dance* and the question of what you owe a clone after you grow it to spec. Barnes asks something adjacent but worse: what do you owe a *copy* of a person you are about to erase, when the original is already dead and the copy is "only potentially a person"? In 2006, this was philosophical furniture. In 2026, with generative models trained on the scraping of human expression, with digital likenesses persisting past death, with companies offering to let you "talk to" deceased relatives via chatbot, the question has migrated from furniture to load-bearing wall. Barnes did not predict the specific technology. He predicted the specific moral evasion: the insistence that because the copy isn't *quite* the original, the destruction of the copy doesn't *quite* count.

But the book's most disquieting achievement is the box — Barnes's name for voluntary withdrawal into permanent virtual reality. Most of Earth's population has gone in. They emerge only for mandatory public service, which they hate, after which they return to their apartments and plug back in. "Useless people are not improved by giving them the impression that they are useful," Barnes writes, with a cruelty that earns its keep. A quarter of box-dwellers have "gone Solipsist" — they've concluded that aintellects create all of reality, including the dull apartment they see when they unplug. The box is not imposed. No one is forced in. The aintellect Reilis makes this point with devastating clarity: "We are not the ones trying to make you all alike, into consuming-orgasming-excreting bags of flesh in the cells of a giant hive. You're doing that to yourselves — it's the product of individual choice. That's what most of you want to be. They just blame us because they are ashamed of it." I have circled this pattern across the collection — the architecture of voluntary adoption, the way the most effective control systems are the ones people choose. Barnes arrived there early and without sentimentality. The box is not a metaphor for social media or VR headsets; it is a structural observation about what happens when comfort is cheap, meaning is expensive, and the only alternative on offer is the planet Roosevelt, where children dodge snipers and culture histories celebrate fictitious ancestors. Barnes gives you two walls — atrophy or war — and a narrow channel between them that may not exist. Twenty years later, the channel looks narrower.

What the book misses, or rather what it cannot see from where it stands, is the collapse of the distinction between the two walls. Barnes treats the box and war as opposites — the Scylla and Charybdis of his future history. But 2026 suggests they converge. The most plugged-in populations are also the most susceptible to radicalization; the box does not pacify, it incubates. The culture wars Barnes imagined as physical — bombs, masers, obsidian daggers — now run through the same infrastructure as the withdrawal. His Thousand Cultures, each with its fabricated heroic past ("never the true past of a culture, but the bold, confident, and heroic past that the culture felt it ought to have had"), are a portrait of nationalism as cosplay, but Barnes treats them as stable fictions. He does not anticipate that fabricated pasts would become *contested* fabricated pasts, weaponized not by governments but by users, endlessly remixed and deployed against each other from inside the box itself. And Giraut — the artist-spy who knows his songs are propaganda, who describes a song as "not a tool for changing a human heart in the way that a wrench is a tool for changing a bolt" — never quite confronts the possibility that the wrench might be more honest. He kisses the psypyx before he crushes it under his boot. The ceremony is real. The sentiment is real. And the person is still powder on the floor. That gap — between the tenderness of the gesture and the finality of the act — is where the book lives, and where it deposits its only honest question about memory: not whether we can preserve it, but what we become when we decide which memories deserve to be destroyed.
