re: The Fractal Prince (really the whole Quantum Thief trilogy), I may be biased, but when I first read it I had 2 reactions: (1) this is the most targeted-at-my-ingroup novel I have ever read (2) nobody outside of my ingroup will get the kajillion references flying around, since Hannu Rajaniemi never bothered footnoting / defending any of them (unlike say what Peter Watts did with Blindsight), so people will think he’s just making up technobabble when he’s not, which means he’ll be generally underappreciated despite the effusive praise (which will be of the generic “he’s so smart” variety), which made my heart sink.
But Gwern not only got it (unsurprisingly), he articulated it better than I ever could, so thanks Gwern:
Hannu makes no concessions to the casual reader, as he mainlines straight into his veins the pre-deep-learning 2010-era transhumanist zeitgeist via Silicon Valley—if it was ever discussed in a late-night bull session after a Singularity University conference, it might pop up here. Hannu stuffs the novels with blink-and-you’ll-miss-it ideas on the level of Olaf Stapeldon. A conventional Verne gun is too easy a way of getting to space—how about beating Project Orion by instead using a nuclear space gun (since emulated brains don’t care about high g acceleration)? Or for example, the All-Defector reveals that, since other universes could be rewriting their rules to expand at maximum speed, erasing other universes before they know it, he plans to rewrite our universe’s rule to do so first (ie. he will defect at the multiversal level against all other universes); whereas beginner-level SF like The Three Body Problem would dilate on this for half a book, Hannu’s grand reveal gets all of 2 paragraphs before crashing into the eucatastrophic ending.
For world-building, he drops neologisms left and right, and hard ones at that—few enough American readers will be familiar with the starting premise of “Arsène Lupin in spaaaace!” (probably more are familiar with the anime Lupin The Third these days), but his expectations go far beyond that: the ideal reader of the trilogy is not merely one familiar with the Prisoner’s Dilemma but also with the bizarre zero-determinant PD strategies discovered ~2008, and not just with such basic physics as quantum entanglement or applications like quantum dots, but exotic applications to quantumauctions & game theory (including Prisoner’s Dilemma) & pseudo-telepathy (yes, those are things), and it would definitely be helpful if that reader happened to also be familiar with Eliezer Yudkowsky’s c. 2000s writings on “Coherent Extrapolated Volition”, with a dash of Nikolai Fyodorovich Fyodorov’sRussian Cosmism for seasoning (although only a dash2).
This leads to an irony: I noted while reading Masamune Shirow’s Ghost in the Shell cyberpunk manga that almost everything technical in the GitS manga turned out to be nonsense despite Shirow’s pretensions to in-depth research & meticulous attention to detail; while in QT, most technical things sound like cyberpunk nonsense and Hannu doesn’t insert any editorial notes like Shirow does to defend them, but are actually real and just so arcane you haven’t heard of them.
For example, some readers accuse Hannu of relying on FTL communication via quantum entanglement, which is bad physics; but Hannu does not! If they had read more closely (similar to the standard reader failure to understand the physics of “Story of Your Life”), they would have noticed that at no point is there communication faster-than-light, only coordination faster-than-light—‘spooky action at a distance’. He is instead employing advanced forms of quantum entanglement which enable things like secret auctions or for coordinated strategies of game-playing (quantum coordination, like treating the particle measurements as flipping a coin and one person does the ‘Heads’ strategy and the other person does the ‘Tails’ strategy does not require communication, obviously, but surprisingly, quantum coordination can be superior to all apparently-equivalent communication-free classical strategies). He explains briefly that the zoku use quantum entanglement in these ways, but a reader could easily miss that, given all the other things they are trying to understand and how common ‘quantum woo’ is.3
Rajaniemi confirmed that Gwern “got it” like nobody else did:
As a longtime fan of gwern ’s work—gwern.net is the best rabbit hole on the Internet—it’s a treat to see this incredibly thoughtful (and slightly spoilery) review of the Quantum Thief trilogy. gwern.net/review/book#quantu… Gwern perfectly nails the emotional core of the trilogy and, true to form, spots a number of easter eggs I thought no one would ever find. This may be my favorite review of all time.
I admire Rajaniemi for pulling it off as you said, but I’m somehow not that surprised. He’s bright (mathematical physics PhD) and has been working at writing-as-craft for a while:
But talking to him about his rapid career, it’s quickly apparent he’s no stranger to being compared to other sci-fi rising stars, having first seriously begun writing in 2002 while studying his PhD as part of writing group called Writers Bloc – which includes authors Charles Stross and Alan Campbell. “It is, and always has been a place with quite a harsh level of criticism,” he says. “But in a healthy and professional way, of course, so it was a good group of people and environment in which to develop.”
I personally got the Quantum Thief trilogy because I’d been blown away by Stross’ Accelerando, wanted more, and saw Stross say of Rajaniemi: “Hard to admit, but I think he’s better at this stuff than I am. The best first SF novel I’ve read in many years.”
