[[thoughts/game theory|coordination failure]] at the level of states. stabilization requirement: strong global governance capable of reliably solving high-stakes coordination problems, even where vital security interests create defection incentives. ### type-2b: cumulative tragedy of the commons when many individually-rational actions sum to civilizational devastation. “worse global warming” - if climate sensitivity were 5x higher, individual actors maximizing economic benefit would collectively destroy civilization. differs from type-2a because no single actor can devastate civilization, but the aggregate effect of widespread behavior reaches the threshold. requires incentives that appeal to substantial fractions of the population (economic gain, convenience). stabilization requirement: global governance plus potentially some preventive policing, depending on observability of individual contributions. ### type-0: inadvertent catastrophe technologies with hidden catastrophic risks that normal caution fails to identify. “surprising strangelets” - if particle accelerators could trigger vacuum decay but this was as easy to overlook as the lithium-7 contribution in the castle bravo test. distinguishes true inadvertence (bad luck/calculation error) from coordination failure. if actors would proceed even with adequate coordination, believing benefits outweigh costs, but they’re wrong. stabilization requirement: unclear - by definition, actors don’t recognize the risk. may require institutional conservatism or outside intervention {{sidenotes[meta]: this seems to require a kind of epistemic humility that scientific institutions actively select against}}. ## the semi-anarchic default condition bostrom defines this as the world order characterized by three features: 1. **limited preventive policing**: states cannot virtually eliminate illegal actions by individuals/small groups, particularly ones >99% of population disapproves 2. **limited global governance**: no reliable mechanism for solving global coordination problems in high-stakes situations where vital national security interests are involved 3. **diverse motivations**: recognizably human distribution of motives at individual and state level, including an “apocalyptic residual” exiting this condition requires closing two fundamental governance gaps - the “micro” gap (individual-level prevention) and the “macro” gap (state-level coordination). ## stabilization and its discontents ### the high-tech panopticon bostrom’s concrete proposal for filling the micro governance gap: “freedom tags” worn by all citizens, equipped with cameras and microphones, continuously uploading encrypted video/audio to cloud for real-time ai analysis. suspicious activity flagged for human review at “patriot monitoring stations.” estimated cost: \~\$140/person/year, less than 1% of global gdp. potentially cost-effective even aside from preventing civilizational catastrophe, due to crime reduction and increased social trust. technical feasibility increasing rapidly - surveillance technology costs falling, ai content analysis improving, storage/bandwidth becoming cheaper. political feasibility unclear and varies by cultural context. might emerge gradually through drift toward transparency, or suddenly in response to visible catastrophic threat. ### the legitimacy problem this raises foucauldian questions about power and subject-formation that bostrom largely brackets. surveillance doesn’t just prevent actions, it disciplines, normalizes, constitutes subjects {{sidenotes[(Focault)]: discipline & punish: “he who is subjected to a field of visibility, and who knows it, assumes responsibility for the constraints of power”}}. the paper acknowledges downsides (totalitarianism risk, chilling effects, loss of privacy) but treats these as separate considerations to be “added to the balance.” but what if surveillance-enabled stabilization is self-undermining? what if the apocalyptic residual is endogenous to the governance structure? ### global governance and hegemonic stability bostrom notes that “effective global governance” need not mean legitimate multilateral institutions - unipolar hegemony capable of unilateral imposition would suffice for stabilization purposes. this echoes realist international relations but applied to existential risk. [[thoughts/coordination|coordination problems]] at civilizational scale may require concentrations of power incompatible with other values (sovereignty, self-determination, pluralism). timing matters critically: international coordination problems can take decades to solve, but vulnerabilities may offer little warning. this creates pressure for developing stabilization capacity before specific threats materialize - building the panopticon in standby mode, accepting totalitarianism risk to hedge against black ball risk. ## circa ai safety wrt implication: - _should not_ unquestioningly assume that all technological progress is beneficial - partial protection can be achieved through _targeted interventions_ to prevent mass production - in case of we want to tune down specific features/behaviour through certain [[thoughts/sparse crosscoders#model diffing|diffing]] patches the framework applies directly to transformative ai scenarios: - **ai as type-1 enabler**: if ai capabilities become broadly accessible, they could enable individuals to cause mass harm (bioweapon design, cyber attacks, manipulation at scale) - **ai as type-2a driver**: [[thoughts/race dynamics|race dynamics]] in ai development create incentives to cut safety corners - first-mover advantages, competitive pressures, security dilemmas between nations - **ai as type-0 risk**: transformative ai might have emergent properties or failure modes not visible during development, analogous to the castle bravo miscalculation [[thoughts/sparse crosscoders#model diffing|model diffing]] and targeted interventions connect to bostrom’s “partial protection” - rather than prevent all ai development (general relinquishment), identify specific dangerous capabilities for differential development. but ai also potentially enables stabilization - advanced ai could power the surveillance/analysis infrastructure needed for high-tech panopticon, or facilitate global coordination through better mechanism design. ### wittgensteinian problems with risk quantification bostrom uses precise thresholds (15% population death, >50% gdp reduction) to define “civilizational devastation.” but these concepts may lack determinate meaning outside historical experience. [[thoughts/Tractatus|tractatus]]: limits of language are limits of thought - we cannot meaningfully assign probabilities to scenarios beyond our conceptual reach. the vulnerability hypothesis requires reasoning about tail risks where our probability estimates are not just uncertain but potentially incoherent. how do we evaluate “extremely likely” when applied to unprecedented civilizational devastation? our calibration breaks down precisely where it matters most. ### the paradox of preventive action if vwh is true, we need stabilization mechanisms before specific threats materialize - the timing problem means waiting for clear danger is too late. but this requires accepting massive costs (surveillance, global governance) based on abstract reasoning about hypothetical scenarios. epistemically: we’re asked to reorganize civilization based on medium-confidence beliefs about low-probability high-impact events in deep uncertainty. politically: how do you build consensus for radical institutional change to prevent disasters that by hypothesis haven’t occurred? ### on what cannot be put back in the urn “we can invent but not uninvent” - but this may be too simple. knowledge can be lost (see roman concrete, greek fire). technologies can become obsolete or economically unviable. social contexts that make applications thinkable can shift. the urn metaphor obscures path dependencies and contextual factors. maybe some balls can only be drawn after others, and some drawings change the urn itself. technological possibility isn’t just about physical law but about social/economic/cognitive infrastructure. ## notes i think what bostrom underweights: 1. **endogenous preferences**: treats human motivation distribution as fixed, but institutions shape preferences. surveillance states may generate resistance identities. just world orders may shrink apocalyptic residual. 2. **legitimacy and stability**: assumes governance capacity can be evaluated separately from legitimacy, but illegitimate power may be inherently unstable or require such repression it generates threats. 3. **positive feedback loops**: technological development might make stabilization easier (better coordination tools, abundance reducing conflict) not just harder. framework is biased toward pessimism. 4. **value lock-in**: permanent global governance or surveillance infrastructure creates path dependence. if we “solve” the vulnerable world problem through authoritarian stabilization, we may lock in suboptimal values forever. though, he got the following right: 1. **the asymmetry of creation/destruction**: genuinely true that destructive capabilities often scale differently than defensive ones. may fundamentally favor offense at technological maturity. 2. **coordination as the crux**: identifies that most catastrophic scenarios involve coordination failure (either at individual or state level), not pure accidents or nature. 3. **the timing problem**: lead time between threat visibility and required institutional capacity is underappreciated. by the time bioweapon threat is obvious, may be too late to build monitoring infrastructure. 4. **moving past techno-optimism**: valuable corrective to naive assumption that all technological progress is beneficial and manageable post-hoc. ## open questions and provocations > \[!question\] on the metaphysics of inevitability > > bostrom assumes technological determinism - “all technologies that can be developed will be developed” - only timing varies. this echoes wittgenstein’s critique of necessity in the {{sidenotes[tractatus.]: “what can be shown cannot be said” - here, what physical law permits cannot be indefinitely prohibited}} but is this metaphysically coherent? could stable equilibria exist where certain discoveries remain permanently inaccessible due to path dependencies, not just delayed? the urn model presupposes all balls are eventually drawable, but what if some require prerequisite draws that change the urn’s structure? > \[!question\] on the asymmetry between type-1 and type-2 vulnerabilities > > bostrom argues type-1 requires eliminating governance gaps at the individual level, type-2 at the state level. but contemporary ai development suggests these collapse - powerful actors racing to build transformative ai face type-2a dynamics (incentives to cut safety corners), yet the technology once developed creates type-1 dynamics (widespread access to powerful capabilities). what happens when black balls simultaneously open vulnerabilities across types? does this require both governance interventions simultaneously, and how do their logics conflict? > \[!question\] on the temporal structure of discovery > > bostrom discusses timing - protective technologies should arrive before destructive ones. but this assumes linear technological development. what about technologies with long fuses? synthetic biology advances today might not reveal civilizational vulnerabilities for decades, only after enough enabling technologies exist. how should we think about “latent black balls” - discoveries that seem gray but become black only in combination with future unknowable developments? this radically undermines the information structure bostrom assumes. > \[!question\] on legitimacy and the apocalyptic residual > > bostrom treats the apocalyptic residual as exogenous - some fixed percentage will always want destruction. but political legitimacy affects this distribution. consider: how many would sabotage a genuinely just global order versus a hegemon’s imposed peace? the paper brackets questions of legitimate authority precisely where they matter most. a world government capable of “decisive action” without legitimacy constraints might generate its own apocalyptic residual among those it oppresses. can stabilization be self-defeating? > \[!question\] on preference modification and technological lock-in > > bostrom dismisses preference modification as insufficient - even doubling altruism only prevents narrow bands of type-2b scenarios. but this assumes preferences and technologies evolve independently. what if certain technological trajectories make preference modification easier? neurological interventions, AI-mediated social coordination, or even just generation effects of growing up under different institutions. bostrom’s framework may be too static - treating 2025 human nature as fixed when the relevant timescale is centuries. ## practical implications if vwh has non-negligible probability, what follows for present action? - **for ai safety**: suggests importance of [[thoughts/alignment|alignment]] work that doesn’t assume benign default outcomes. also highlights governance/coordination challenges, not just technical safety. - **for biosecurity**: targeted interventions (monitoring DNA synthesis, personnel screening) are stopgaps. need to consider whether biotech trajectory requires more fundamental governance changes. - **for institutional design**: should we be developing surveillance/coordination capacity in “standby mode” before specific threats materialize? what safeguards make this less dangerous? - **for risk assessment**: need frameworks for reasoning about threats where precision is impossible but decisions can’t be deferred. how do we avoid both paranoid overreaction and complacent underreaction? > \[!question\] Question > > - can we develop metrics for how close we are to exiting the semi-anarchic default condition in each dimension? > - what institutional forms could provide global governance or preventive policing capacity while preserving meaningful pluralism and liberty? > - how do we reason about the probability of vwh itself? what evidence would update us significantly either direction? > - are there alternative stabilization mechanisms bostrom hasn’t considered? (cultural evolution, preference modification, defensive technological trajectories)
