Free Glasshouse by Charles Stross

society we are simulating. They’d do it this way, with a face-to-face meeting, so . . . if you would all like to take seats?”
    We take a while to sort ourselves out. I end up in the front row, sitting between Big Guy and a female with freckled pale skin and coppery red hair, not unlike Linn, but wearing a cream blouse and a dark gray jacket and skirt. It’s not a style I can make any sense of—it’s vertically unbalanced and, frankly, a bit weird. But it’s not that different from what they’ve given me to wear, so I suppose it must be historically accurate. Have our aesthetics changed that much? I wonder.
    The person on the podium gets started. “I am Major-Doctor Fiore, and I worked with Colonel-Professor Yourdon on the design of the experimental protocol. I’m here to start by explaining to you what we’re trying to achieve, albeit—I hope you’ll understand—leaving out anything that might prejudice your behavior within the trial polity.” He smiles as if he’s just cracked a private joke.
    â€œThe first dark ages.” He throws out his chest and takes a deep breath when he’s about to say something he thinks is significant. “The first dark ages lasted about three gigaseconds, compared to the seven gigaseconds of the censorship wars. But to put things in perspective, the first dark ages neatly spanned the first half of the Acceleration, the so-called late-twentieth and early-twenty-first centuries in the chronology of the time. If we follow the historical record forward from the pretechnological era into the first dark age, we find we’re watching humans who lived like technologically assisted monkeys—very smart primates with complex mechanical tools, but basically unchanged since the species first emerged. Then when we look at the people who emerged from the first dark age, we find ourselves watching people not unlike ourselves, as we live in the modern era, the ‘age of emotional machines’ as one dark age shaman named it. There’s a gap in the historical record, which jumps straight from carbon ink on macerated wood pulp to memory diamond accessible via early but recognizable versions of the intentionality protocols. Somewhere in that gap is buried the origin of the posthuman state.”
    Big Guy mutters something under his breath. It takes me a moment to decode it: What a pompous oaf. I stifle a titter of amusement because it’s no laughing matter. This pompous oaf holds my future in his hands for the next tenth of a gigasec. I want to catch his next words.
    â€œWe know why the dark age happened,” Fiore continues. “Our ancestors allowed their storage and processing architectures to proliferate uncontrollably, and they tended to throw away old technologies instead of virtualizing them. For reasons of commercial advantage, some of their largest entities deliberately created incompatible information formats and locked up huge quantities of useful material in them, so that when new architectures replaced old, the data became inaccessible.
    â€œThis particularly affected our records of personal and household activities during the latter half of the dark age. Early on, for example, we have a lot of film data captured by amateurs and home enthusiasts. They used a thing called a cine camera, which captured images on a photochemical medium. You could actually decode it with your eyeball. But a third of the way into the dark age, they switched to using magnetic storage tape, which degrades rapidly, then to digital storage, which was even worse because for no obvious reason they encrypted everything. The same sort of thing happened to their audio recordings, and to text. Ironically, we know a lot more about their culture around the beginning of the dark age, around old-style year 1950, than about the end of the dark age, around 2040.”
    Fiore stops. Behind me a couple of quiet conversations have broken
