Total Privacy Societies: The Quantum Thief by Hannu Rajaniemi

I love books that explore interesting concepts. The Quantum Thief by Hannu Rajaniemi was a little bit of an impulse buy for me. You see, I have a running Amazon wish list. Whenever I stumble upon very favorable book reviews, or get good reading suggestions I add them on. Then when it’s time for me to order up a batch of new books, I just pick the best sounding titles from my list. All the research is done ahead of time. This particular book however showed up in the Amazon suggestion box. “If you like these titles, you may also like The Quantum Thief” it said. I read the content blurb, glanced at the reviews and went “why the hell not”. So it landed in my shopping cart, and shortly thereafter on my desk.

Book cover featuring the action chick and the gentleman thief.

I’m actually rather glad I bought it. It’s not necessarily a great book, but I would classify it as interesting. The plot and characters are more or less your usual space opera affair. You have a gentleman thief, a brilliant, a honor bound action chick and a likable sentient starship. For my tastes they were all a bit too perfect – too smart, too much on their game, to flawless. What can I say – I like my characters to be deeply flawed, twisted and fucked up. Granted, the main protagonist is not a complete Joshua Calvert – he is a bit more complex than that. But he is somewhere in that neighborhood at times. Of course this something you could easily forgive considering this is Rajaniemi’s first novel. As a debut story it actually holds up quite well. The author has a way with words, his descriptions are vivid and colorful and he prefers to show rather than tell.

What I liked the most about Rajaniemi’s novel is his concept of a society based on total personal privacy. Most of the story takes place in a peculiar roaming city on Mars. It is a place where people go to be forget and be forgotten. It is a place to start a new life. It’s one of the last bastions of humanity not controlled by post singularity transapient minds. It is a place where time flows slowly and human achievements actually matter. It is where artists, poets, musicians and architects flourish without having to compete against superhuman intelligences. They call this place the Oubliette.

If you happen to speak French or ever took some classes in this romantic language you will probably recognize the literal meaning of that word to roughly translate to something along the lines of “forgotten place”. But the word also has more popular connotations. I don’t want to spoil anything but Rajaniemi does tip his hand a bit with his name choices sometimes – I can’t decide if this is a rookie mistake (he does like to borrow exotic foreign words in lieu of neologisms), or just sloppy foreshadowing.

The idea behind Oubliette is rather fascinating. It provides all it’s citizens and visitors with technological means of maintaining absolute privacy. If you don’t want to be seen, you you won’t be. If you don’t want to leave any public trail, you wont. It is a society in which two roommates can share the same flat and only see each other on holidays, via invitation.

Rajaniemi describes the system that allows this sort of privacy to exists quite extensively, but he does it indirectly. There is no exposition info dump – instead the feeds you the information gradually throughout the novel. To me this was probably the most interesting part of the novel – figuring out how this technology works, based on hints and descriptions scattered throughout the text.

There are basically two elements which allow citizens of Oubliette to control their privacy. One of them is exomemory – a ubiquitous cloud storage service accessible over the air from any point in the city. Exomemory records and logs everything that happens in the city via a deep sensory layer that covers every inch of the habitable space, as well as through wetware implants of it’s citizens. Every thought, every gesture, every twitch and bodily function is recorded, tagged, and placed in the cloud. I know, this sounds like the opposite of privacy, but bear with me. The interesting part is that every bit of information logged by the city is encrypted. External memories from public places are available to everyone upon request, and they are essentially a substitute of the internet and news services. Memories captured on a private property or by by implants of an individual are encrypted with their private key and thus inaccessible to anyone else.

The second part of equation is Gevulot (from the yiddish word for borders) which is a hardware/software layer that allows you to generate, share or obtain keys for memories, as well as preserve your privacy while in public. It includes special wetware circuits, and artificial privacy organs that allow citizens to instinctively feel how much they are sharing, and with whom. Each memory or thought gets it’s own unique key so an individual’s gevulot will on average handle thousands if not millions of them – but thanks to powerful abstraction managing and sharing the keys is extremely easy.

Yes, people can share their memories just like we share notes. Since all of them are stored in the cloud, gifting someone a piece of your memories is just a matter of key exchange.

But that’s only one of gevulot’s functions. So for example, if you wanted to take a leisurely stroll through the park without being seen or disturbed you could completely shroud yourself from both the city sensory layer as well as well as praying eyes of strangers. Your walk would still be on the record but your identity would be encrypted and locked with your keys.

When two citizens randomly meet on the street their gevulot automatically exchanges privacy preferences and negotiates specific concessions. If someone does not want to be seen by you, then your gevulot will automatically blur/mute them out by interfacing with your visual cortex. If they wish to talk to you, then you will have to negotiate a gevulot contract which specifies whether this is going to be a public or private conversation, whether or not it’s contents can be shared with others, how much of it will be remembered by both parties, whether emotional reactions should be shared or if facial expressions and voice inflections should be algorithmically normalized.

How does such society hold up? Quite well apparently. Rajaniemi portrays Oubliette as a rather peaceful backwater populated by idealists and artists. It does not even have a regular police force. One would think that for some people the complete privacy offered by gevulot would be like finding the Ring of Gyges. You would expect this sort of place to attract all sort of deviants – thieves, serial killers, sociopaths, con artists. But there is almost none of that. While there is crime, it is mostly perpetrated by outsiders – mind thieves who siphon out talented individuals to be later used as virtual slave workers. Those are kept in check by a rag-tag group of idealistic vigilantes using smuggled-in advanced nano-technology and wearing colorful masks, and amateur part time detectives who use Sherlock Holmes school of deduction to skirt around gevulot barriers.

Then again the lack of deviants and sociopaths in this police-less state starts making more sense when it is revealed that…


Oubliette is actually a panopticon – a total invigilation state built around mere illusion of total privacy. I mean what did you expect from a place that records absolutely everything in a centralized could service, and takes it’s name from a french word commonly used to refer to a dungeon. The elite group of mysterious “cryptarchs” holds all the master keys to the exomemories, and quietly deals with anyone who dares to rock the boat.


The Quantum Thief has more interesting ideas. Rajaniemi proposes an intriguing system which solves two post-singularity problems in one swoop. It provides a viable currency that retains value in post-scarcity economies and gives immortals something that prevents them from getting bored with their endless lives, and makes them cherish simple pleasures of life.

The main currency in Oubliette is time. Every citizen is allotted certain amount of time to live. This time can be traded among individuals for goods and services. If you are good at something or you can provide others with something useful, you can gain more time which you can in turn blow on toys, idle pleasures and etc. It is more or less crypto-currency based on very secure quantum computing algorithms and very difficult to forge. Once your time runs out, your gevulot switches off your body and you wake up as a “Quiet”.

Oubliette is a society of immortals, but it does have an afterlife of sorts. When you become a Quiet your speach centers of your brain are deactivated so you are unable to speak, write or even mime. You are given a biotic or mechanical body tailored for a specific task and some job to do. You sweep the streets, you build houses, you maintain city infrastructure, you clean the sewers – whatever is needed at the time. There are no cushy desk jobs – everyone gets allotted equally dirty and back braking labor regardless of their social class or status. As a Quiet you slowly earn your time back by doing menial, uninteresting jobs so that other citizens can live care free lives. Once your accumulate enough time, you get back your human body, and you get to do it all over again.

It is a very clever idea. Such an artificially imposed life cycle offers stability and grounds many folks who otherwise would not be able to deal with endless life. It serves to temper those whose tastes get too decadent, wet their appetite for simple pleasures of life, and the back breaking work may teach them some humility. Not to mention that it allows citizens of Oubliette live leisure, care free lives pursuing arts and hobbies without the need to maintain vast armies of robotic drones, and artificial intelligences to maintain them.

The Quantum Thief gets my recommendation. It’s a good read filled with some intriguing ideas and reflections on post-singularity societies. It is not perfect: the plot and characters are a bit lacking and some of the ideas could have been more developed. But it is forgivable considering the novel is a debut work of a fledgling new author.

Not to mention that this is probably the only novel you will read this year that features a walking city. Yes, a city with legs. Eat your heart out Howl, Oubliette has a whole city to your puny castle.

    I must say, the concept of “Quiet” seems at least in part, inspired by the whole death-and-rebirth idea from Eastern Belief systems. Include a provision for intensity/”backward-ness” of allotted labour being a function of peak-rate of earning when alive (peak productivity), and a crimes/misdeed count, and BAM! We have Karma.

    @ Dileep:

    Heh, true. I think one of the points the author was making was that the Quiet system was used as an equalizer. After death, everyone would work just as hard – the former millionaires, nobles, commoners, criminals, etc…

    So there was no incentive to be particularly good. The incentive was to use your time well, and enjoy life – because you had to work it off.

    I think the punishment for crimes was time reduction and early quiet. This of course meant that your entire mind would have to go through exomemory before being uploaded into a Quiet body – at which point [ SPOILERS] you would be at the mercy of the cryptarchs. If you were a threat to them, they would just “adjust” your attitude a bit and make you a “better” person. [/SPOILERS]

    “If you want to leave any public trail, you wont.”

    That sentence is missing either an “even” or a “don’t” to make sense.

    Also, are the spoiler tags supposed to actually hide the spoilers, or are we suppose to interpret them in our meatbrains?

    @ nitro2k01:

    Ok, I fixed it.

    Spoler tags were metabrains only but I made spoilers hidden now. I think simple tricks like changing the font color do not work in most RSS readers so I figured I will just trust people not to read the spoilage. :)

    If you put some blank space between the first spoiler tag and the beginning of the actual spoiler text, it’ll help stop folks from accidentally reading it. I know I sometimes pick up several lines of text at once when reading so that might be beneficial. (I’m not using an RSS reader so I didn’t read the spoilers, but you get what I’m going for.)

    Exomemory reminds me a little of tarsnap, among other things. I’m kind of perplexed by the idea of the whole society’s interactions being government by a single Facebook-like system. Everything appears to be in control of the indivuals, but a lot clearly isn’t. (The cload can actually affect what you see and hear through implants in your brain!)

    @ Luke Maciak:
    I’m awful at not reading stuff. When I see a spoiler warning like that I have to literally turn my head away in panic and scroll the page so that the page ends/starts right where the spoiler warning starts/ends.

    It’s like the concept “don’t think of an elephant”. Googling it seems to mostly lead you to a book on American politics, so I’ll describe the concept briefly: If you say “don’t think of an elephant”, the brain of the listener will start thinking about elephants, whether xe wants or not, as a spontaneous reaction.

    Normally, I wouldn’t care much, but I can actually see myself reading this book so I didn’t want to spoil it for myself.

    I just watched a movie that took the idea of time as a currency and Hollywood-ized it into pseudo-futuristic Bonny/Clide story with Justin Timberlake. I remembered that you reviewed something similar so I had to check. The movie already had two plagiarism claims.

    @ Victoria:

    I heard good things about this movie (and by that, I mean that I’ve been told it’s not horrible). I actually want to see it because, hell – it’s about immortality. Totally up my alley.

    That said, I don’t think that a plagiarism claim would stick. Rajaniemi’s book is far future, post singularity story with action taking place on a mobile city, walking the surface of Mars. The whole bit about time as currency is only one of the major topics, and the movie handles it differently. From the trailer it appears that when your time runs out you just die. In Quantum Thief it simply means it is your turn to do a work-shift in a mute, lumbering robotic body. You do a decade or two of hard manual labor, and then you get a human body back, and an allotment of time to waste on simple pleasures. I don’t think they plagiarized the book.
