I am at a loss for words to describe my lack of eagerness to go there. - Charles Stross

Most of what we get up to in the Laundry is symbolic computation intended to evoke decidedly nonsymbolic consequences. But that’s not all there is to...well, any sufficiently alien technology is indistinguishable from magic, so let’s call it that, all right? You can do magic by computation, but you can also do computation by magic. The law of similarity attracts unwelcome attention from other proximate universes, other domains where the laws of nature worked out differently. Meanwhile, the law of contagion spreads stuff around. Just as it’s possible to write a TCP/IP protocol stack in some utterly inappropriate programming language like ML or Visual Basic, so, too, it’s possible to implement TCP/IP over carrier pigeons, or paper tape, or daemons summoned from the vasty deep.

“But then—you’re telling me they brought unrestricted communications with them?” he asked.
“Yup.” Rachel looked up from her console. “We’ve been trying for years to tell your leaders, in the nicest possible way: information wants to be free. But they wouldn’t listen. For forty years we tried. Then along comes the Festival, which treats censorship as a malfunction and routes communications around it. The Festival won’t take no for an answer because it doesn’t have an opinion on anything; it just is.”
“But information isn’t free. It can’t be. I mean, some things — if anyone could read anything they wanted, they might read things that would tend to deprave and corrupt them, wouldn’t they? People might give exactly the same consideration to blasphemous pornography that they pay to the Bible! They could plot against the state, or each other, without the police being able to listen in and stop them!”
Martin sighed. “You’re still hooked on the state thing, aren’t you?” he said. “Can you take it from me, there are other ways of organizing your civilization?”
“Well—” Vassily blinked at him in mild confusion. “Are you telling me you let information circulate freely where you come from?”
“It’s not a matter of permitting it,” Rachel pointed out. “We had to admit that we couldn’t prevent it. Trying to prevent it was worse than the disease itself.”
“But, but lunatics could brew up biological weapons in their kitchens, destroy cities! Anarchists would acquire the power to overthrow the state, and nobody would be able to tell who they were or where they belonged anymore. The most foul nonsense would be spread, and nobody could stop it—” Vassily paused. “You don’t believe me,” he said plaintively.
“Oh, we believe you alright,” Martin said grimly. “It’s just—look, change isn’t always bad. Sometimes freedom of speech provides a release valve for social tensions that would lead to revolution. And at other times, well—what you’re protesting about boils down to a dislike for anything that disturbs the status quo. You see your government as a security blanket, a warm fluffy cover that’ll protect everybody from anything bad all the time. There’s a lot of that kind of thinking in the New Republic; the idea that people who aren’t kept firmly in their place will automatically behave badly. But where I come from, most people have enough common sense to avoid things that’d harm them; and those that don’t, need to be taught. Censorship just drives problems underground.”
“But, terrorists!”
“Yes,” Rachel interrupted, “terrorists. There are always people who think they’re doing the right thing by inflicting misery on their enemies, kid. And you’re perfectly right about brewing up biological weapons and spreading rumors. But—” She shrugged. “We can live with a low background rate of that sort of thing more easily than we can live with total surveillance and total censorship of everyone, all the time.” She looked grim. “If you think a lunatic planting a nuclear weapon in a city is bad, you’ve never seen what happens when a planet pushed the idea of ubiquitous surveillance and censorship to the limit. There are places where—” She shuddered.

“Prosthetic Morality Enforcement. The idea is that by analogy, if a part of your body is deficient or missing, you can use a prosthetic limb or artificial organ. Well, our ability to make moral judgements is hard-wired, but it’s been so far outrun by the demands of complex civilization that it can’t keep up. For example...have you ever wondered why discussions in chat rooms or instant messaging turn nasty so easily? Or wander off topic? It’s because the behavioural cues we use to trigger socially acceptable responses aren’t there in a non-face-to-face environment. If you can’t see the other primate, your ethical reasoning is impaired because you can’t build a complete mental image of them—a cognitive frame. It’s why identity theft and online fraud are such a problem: There’s no inhibition against robbery if the victim is faceless. So we need some kind of prosthetic framework to restore our ability to interact with people on the net as if they’re human beings we’re dealing with in person.
