## Overview William MacAskill is a Scottish philosopher, co-founder of the [[Effective Altruism]] movement, and the figure most responsible for its longtermist capture. Born William Crouch (adopting the surname MacAskill as an adult), he holds the position of Associate Professor of Philosophy at the University of Oxford. MacAskill authored the influential texts *Doing Good Better* (2015) and *What We Owe the Future* (2022), and co-founded multiple institutional pillars of the EA movement: [[80,000 Hours]], [[Giving What We Can]], the [[Centre for Effective Altruism]], and the [[Global Priorities Institute]]. MacAskill's career exemplifies both EA's early promise and its catastrophic failure modes. He took utilitarian philosophy and built it into an operational social movement with institutional infrastructure, a talent pipeline, and access to billions of dollars. His mentorship of [[Sam Bankman-Fried]] and the subsequent FTX collapse represents the endpoint of EA's longtermist logic: a framework for moral reasoning that provided no principled constraints on fraud or massive risk-taking. MacAskill is the person who made [[TESCREAL]] operational. ## Early Life and Philosophical Formation MacAskill was educated at St Andrews University and later studied at Cambridge before completing a DPhil in philosophy at Oxford. His intellectual formation occurred within the nexus of [[Peter Singer]]'s utilitarian ethics and the rationalist analytical philosophy tradition. His early interests centered on moral philosophy, particularly questions of how to do the most good with limited resources. The crucial intellectual input came from Singer's arguments that affluent people in wealthy countries have strong moral obligations to help those suffering from global poverty. Singer's "drowning child" argument — that failing to save a drowning child is as morally culpable as allowing a distant child to die of preventable disease — became foundational to MacAskill's worldview. He accepted Singer's conclusion that geographical distance or impersonal relationships don't diminish moral responsibility. ## Co-Founding the Institutions: Giving What We Can and 80,000 Hours In 2009, MacAskill co-founded [[Giving What We Can]] with [[Toby Ord]]. The organization centered on a simple pledge: members committed to donating at least 10% of their income to effective causes. This translated Singer's obligation into an institutional form. Giving What We Can became the membership organization and moral foundation of EA, turning ethical conviction into a membership metric. In 2011, MacAskill founded [[80,000 Hours]], a career advice organization premised on the idea that career choice is one of the most important moral decisions a person makes. The name refers to the approximate number of hours one works over a career. The organization's implicit theory: if each person can be directed toward a higher-impact career path, the aggregate effect on the world is massive. The talent pipeline function became critical to EA's growth — 80,000 Hours didn't just provide advice; it funneled talent into longtermist research positions, AI safety organizations, and later, FTX. In 2012, MacAskill co-founded the [[Centre for Effective Altruism]] (CEA), the movement's coordination hub. CEA organized [[EA Global]] conferences, provided infrastructure to EA groups worldwide, and served as the ideological center of the movement. This institutional triumvirate constituted the early EA movement's practical apparatus: a pledge organization (GWWC), a talent pipeline (80,000 Hours), and a coordination center (CEA). The institutions were nested — members of GWWC were encouraged to use 80,000 Hours' career advice, and both were coordinated through CEA. ## Doing Good Better (2015): Popularizing Effective Altruism MacAskill's first book, *Doing Good Better*, published in 2015, was the definitive popularization of [[Effective Altruism]] for a mainstream audience. The central arguments: 1. Most charitable giving is ineffective or only marginally effective 2. Some interventions are orders of magnitude more cost-effective than others 3. You should use evidence and quantitative reasoning to direct your giving 4. Impact can be measured and compared across domains The book introduced the concept of "earning to give" — the argument that, for some people, it can be more ethical to take a high-paying job in finance, technology, or business and donate most of the proceeds than to work directly in the nonprofit sector. The reasoning: if you can earn $200,000 per year and donate $150,000 of it to highly effective charities, you might have more impact than earning $50,000 working directly for a nonprofit. This argument would prove catastrophic in its consequences when applied to cryptocurrency by [[Sam Bankman-Fried]]. The book also emphasized EA's evidence-based approach. At this stage, EA's flagship cause areas were global health interventions: insecticide-treated bednets for malaria prevention, deworming programs, and direct cash transfers. These were interventions with clear evidence bases and measurable effects. *Doing Good Better* positioned these as exemplars of effective altruism. MacAskill became EA's charismatic public face — a charismatic young philosopher making consequentialism intellectually accessible and morally urgent. The book's success demonstrated that there was a substantial audience for arguments about effective altruism and rational philanthropy. ## The Longtermist Turn: Redirecting the Movement Beginning in the mid-2010s, MacAskill's thinking underwent a fundamental shift that would redirect EA's entire trajectory. The problem: if you accept that EA's current cause areas (global health, poverty reduction) are genuinely important, and if you accept utilitarian logic, then why aren't you working on the causes that affect the most people — the billions of future humans who will exist in the coming millennia? This reframing, articulated in collaboration with [[Hilary Greaves]], became the foundation for [[Longtermism]]. The argument structure is simple but has enormous implications: 1. If future people will exist, they matter morally equally to people who exist now 2. The number of future people could be vastly larger than the number of present people 3. If the numbers are vastly larger, then the expected moral value of affecting the long-term trajectory of civilization vastly exceeds the expected value of present-day interventions 4. Therefore, EA should redirect toward long-term causes: existential risk reduction, the prevention of civilizational collapse, ensuring humanity reaches its potential The implications for cause prioritization are radical. Malaria prevention saves lives — but each life saved represents perhaps 80 additional years of existence. If humanity goes extinct or enters irreversible civilizational collapse, the loss is astronomical: potentially trillions of future people never existing. By this logic, preventing existential risk dominates as a cause area. This represents a fundamental inversion of EA's original empiricism. Global health interventions have measurable, near-term outcomes. Longtermist interventions (AI safety, existential risk research, speculative "cause areas") are far removed from direct evidence. You cannot measure or verify the impact of a longtermist intervention in any concrete way. The shift from "proven interventions with measurable impact" to "speculative long-term interventions" is not merely a change of focus — it's a fundamental epistemological shift away from empiricism. In 2018, MacAskill founded the [[Global Priorities Institute]] at Oxford to formalize and legitimize longtermist research. The institute provided academic respectability to what is essentially apocalyptic speculation. MacAskill co-authored "The Case for Strong Longtermism" with Hilary Greaves, formalizing the philosophical argument. The longtermist turn represents the "capture" of EA by speculative existential risk framings. Early EA had a disciplinary approach: you made a claim, cited evidence, and were prepared to defend it quantitatively. Longtermism operates in a fundamentally different epistemic register — it is apocalyptic philosophy, not evidence-based altruism. ## What We Owe the Future (2022): The Longtermist Manifesto MacAskill's second book, *What We Owe the Future*, published in August 2022, is the definitive statement of longtermist ideology. The core arguments: 1. **Future people matter morally** — Standard utilitarian consequentialism, extended to all potential future people 2. **We live at a hinge of history** — MacAskill argues we live at a uniquely pivotal moment where humanity's trajectory is not yet locked in. Our actions now could determine whether humanity reaches a flourishing far future or enters civilizational collapse 3. **We have obligations to the long-term future** — If we truly believe future people matter, we must act to ensure a flourishing long-term future The book is written with MacAskill's characteristic intellectual charm and moral earnestness. It presents longtermism not as a speculative fringe view but as the obvious implication of basic moral principles. It frames present-day altruistic work as parochial and myopic compared to the grandiose vision of shaping the long-term trajectory of civilization. The book was endorsed by [[Elon Musk]], who tweeted: "Worth reading. This is a close match to my philosophy." Coming from the world's richest man, the endorsement carried enormous cultural weight. The timing proved darkly ironic. The book launched in August 2022 on a wave of promotion and publicity partly funded by FTX. Three months later, in November 2022, FTX collapsed spectacularly. The book that had become the flagship text of longtermist ideology was suddenly tainted by association with fraud and catastrophic financial recklessness. ## The SBF Relationship: The Moral Crucible The relationship between William MacAskill and [[Sam Bankman-Fried]] represents the central crisis of effective altruism and the most damaging critique of longtermist ideology. This relationship must be understood in depth because it reveals the internal logic of EA's failure modes. ### The Encounter and Mentorship MacAskill met SBF when SBF was a student at MIT. SBF had already developed strong consequentialist views (influenced by reading utilitarian philosophy and SBF's parents' moral philosophy work). MacAskill directly encouraged SBF to pursue the "earning to give" path — to make as much money as possible in order to donate massive amounts to EA causes. This was not incidental mentorship. SBF has stated in multiple contexts that MacAskill was the single most influential person in directing him toward EA and the earning-to-give path. SBF took seriously MacAskill's argument that earning money ethically, then donating it to high-impact causes, was the most consequentialist decision he could make. MacAskill connected SBF with members of what would become Alameda Research. The infrastructure of SBF's company was built in dialogue with the EA community. SBF became FTX's CEO and co-founder of Alameda Research, ostensibly to amass wealth that would be donated to EA causes. ### FTX as EA's Largest Funder By 2021-2022, FTX and Alameda Research became EA's largest source of funding by a vast margin. The FTX Future Fund distributed hundreds of millions of dollars to longtermist causes: AI safety research, biosecurity, animal welfare, and other explicitly longtermist areas. The concentration was catastrophic. EA's funding became dependent on FTX. Estimates suggest FTX and Alameda represented approximately 35% of all funding flowing to EA-aligned organizations. This is not merely a large funder — it is structural dependence. Organizations that had grown to depend on FTX funding had few fallback options. Moreover, the distribution of FTX funding was explicitly longtermist. The FTX Future Fund, run by SBF and influenced by longtermist EA figures, directed capital toward the most speculative, longest-term causes. This meant the shape of EA's cause prioritization was increasingly determined by FTX's funding decisions. The organizations that received FTX money thrived; those that didn't (including some global health focused organizations) stagnated. ### The Pre-Collapse Warnings In November 2022, *Time* magazine reported that EA leaders had been warned about SBF's unethical and potentially fraudulent behavior as early as 2018. Some EA figures expressed concerns about his rapid rise, his aggressive business practices, and his willingness to engage in what appeared to be deceptive behavior. These warnings were not acted upon systematically. The structural incentive was clear: SBF was the goose laying golden eggs. To investigate or criticize him risked losing hundreds of millions in funding. Whether consciously or not, EA's institutions had constructed themselves in a way that penalized scrutiny of their largest funder. ### The Collapse and MacAskill's Response In November 2022, FTX collapsed catastrophically. The company's collapse revealed that Alameda Research had been engaged in massive fraud: misappropriating customer funds, engaging in undisclosed related-party transactions, and constructing an elaborate false accounting system to hide the misappropriation. SBF was arrested, extradited to the United States, convicted of fraud, and sentenced to a substantial prison term. FTX's estimated value of $32 billion evaporated. MacAskill's initial response was to tweet that he was "shocked" by the collapse. Critics immediately noted the hollowness of this response. MacAskill had spent the previous weeks promoting *What We Owe the Future* using FTX's promotional apparatus and celebrity power. He had directly mentored SBF toward the "earning to give" philosophy. He had built an institutional apparatus that became dependent on FTX funding. And yet the response was shock and surprise. ### The Moral Architecture of Failure The SBF-MacAskill relationship reveals something crucial about the internal logic of effective altruism and longtermism. MacAskill did not commit fraud. But he created the philosophical framework that SBF used to justify it. The framework operates as follows: 1. **Expected value reasoning applied to massive scales**: If you accept longtermist logic, then small probabilities of affecting civilization-scale outcomes have expected values that dwarf ordinary moral concerns. A 0.1% chance of affecting the long-term trajectory of civilization is worth immense present-day risk-taking. 2. **Earning to give as moral justification**: The argument that maximizing income in order to donate is the most consequentialist decision available removes ordinary ethical constraints on how you earn the money. If you're earning to give, the source of the income becomes morally secondary to its eventual donation. 3. **Utilitarian expected value with no side constraints**: Utilitarian calculation applied globally, without side constraints (legal, deontological, rights-based constraints), produces a framework where massive fraud might be justified if the expected value of the fraud's proceeds outweighs the expected harm. SBF, in interviews and court filings, articulated a worldview that was unmistakably longtermist and utilitarian. He spoke of taking massive risks because the stakes (civilization's long-term future) were so high. He justified ethically questionable behavior by appealing to the magnitude of EA's cause areas. MacAskill created the philosophical architecture. SBF built the practical instantiation. The question of moral responsibility becomes acute: at what point is a philosopher responsible for how their ideas are applied by prominent practitioners? ## The Post-FTX Reckoning Following the FTX collapse, EA underwent a period of crisis and restructuring: ### Institutional Reorganization Effective Ventures (the umbrella organization for CEA, 80,000 Hours, and Giving What We Can) agreed to a $26.8 million settlement with the FTX bankruptcy estate. The settlement represented both a recognition of the organizations' dependence on tainted funds and an acknowledgment of wrongdoing in governance and oversight. Subsidiary organizations began the process of spinning off into independent entities. The Centre for Effective Altruism underwent significant internal restructuring. 80,000 Hours attempted to maintain organizational integrity while addressing questions about its funding sources. Giving What We Can faced credibility questions given its association with massive fraud through EA's institutional apparatus. ### Reputational Damage MacAskill's personal reputation was severely damaged. He had been the charismatic public face of EA; he was now associated with having mentored its most prominent fraudster. The *What We Owe the Future* book tour became awkward. Speaking engagements were cancelled or faced significant protests. More fundamentally, the FTX collapse threw into crisis the entire longtermist project. If longtermism could produce a framework where someone like SBF felt justified in committing fraud "for the long-term future," what does that say about longtermism's internal coherence? ### Questions of Accountability The question remains unresolved: What level of accountability should attach to MacAskill personally? He did not commit fraud. But he: - Directly mentored SBF toward earning to give - Built institutional structures that became dependent on FTX funding - Promoted books and ideas using FTX's promotional power weeks before its collapse - Failed to systematically investigate early warnings about SBF's conduct - Positioned longtermism as intellectually serious while the movement's largest funder was engaged in massive fraud These are questions without clean answers. They are the substantive moral questions the EA movement has largely avoided addressing directly. ## The Institutional Empire MacAskill founded or co-founded nearly all of the major institutional infrastructure of the effective altruism movement: ### [[Giving What We Can]] (2009) Co-founded with [[Toby Ord]], this membership organization centers on the 10% giving pledge. It provides the moral foundation and community infrastructure for individual effective altruists. It has facilitated the distribution of hundreds of millions of dollars to EA-prioritized causes. ### [[80,000 Hours]] (2011) The talent pipeline of effective altruism. Provides career advice and guidance to direct talented people toward high-impact careers. Functions as both a practical career guidance service and an ideological mechanism for channeling talent into EA-aligned organizations. The organization's influence on career trajectories of thousands of people is substantial and largely unmeasured. ### [[Centre for Effective Altruism]] (2012) The movement's coordination hub. Organizes [[EA Global]] conferences (the largest gatherings of the EA community), provides infrastructure to local EA groups, publishes the EA Forum (the primary hub for movement discussion), and functions as the ideological and institutional center of effective altruism. ### [[Global Priorities Institute]] (2018) Housed at Oxford, this research institute formalizes longtermist scholarship into an academic discipline. Its existence represents a remarkable institutional achievement: taking speculative philosophical claims and grounding them in academic infrastructure, grant funding, and research positions. ### [[Forethought Foundation]] (2019) A funding organization explicitly focused on longtermist research and cause areas. Represents the operationalization of longtermist priorities into a funding apparatus. ### [[Effective Ventures]] The umbrella organization encompassing CEA, 80,000 Hours, and Giving What We Can. Functions as EA's institutional holding company. This constellation of organizations constitutes the infrastructure of effective altruism. MacAskill's role in founding or co-founding most of them makes him the person most responsible for EA's institutional form. He is not merely a prominent thinker within EA — he is the architect of its institutional apparatus. ## Function in TESCREAL MacAskill represents the crucial bridge between academic philosophy and operational social movement. He took ideas from: - [[Nick Bostrom]]'s work on existential risk and civilizational fragility - [[Peter Singer]]'s utilitarian ethics and arguments about moral obligation - The rationalist community's emphasis on expected value reasoning and Bayesian analysis - Oxford academic philosophy's tradition of rigorous argumentation And he synthesized these into an operational social movement with: - Institutional infrastructure (CEA, 80,000 Hours, GWWC) - A talent pipeline (80,000 Hours directing people into EA careers) - Funding networks (connecting mega-donors like [[Dustin Moskovitz]] and [[Holden Karnofsky]] with cause areas, and later, FTX) - Academic legitimation (the Global Priorities Institute) - Cultural cachet (books, TED talks, endorsement by [[Elon Musk]]) He is the person who made [[TESCREAL]] operational. TESCREAL exists as academic papers, internet subcultures, and informal networks; MacAskill built the institutional machinery that translates these ideas into real resource allocation and career direction. In [[The Unholy Alliance]], this function is crucial: MacAskill is the figure who provides moral legitimacy to tech billionaires' philanthropic agendas. When [[Elon Musk]] or [[Dustin Moskovitz]] or [[Sam Bankman-Fried]] wanted moral legitimacy for their resource allocation decisions, they could point to MacAskill's philosophical arguments. Longtermism provided a moral vocabulary that made billionaire funding of speculative AI safety research sound like saving civilization. ## The Philosophical Critiques MacAskill and longtermism face multiple sophisticated critiques: ### The Expected Value Problem The core problem: utilitarian expected value reasoning, applied globally and without side constraints, produces conclusions that many find morally abhorrent. If you truly believe that massive fraud is justified if the expected value of its proceeds (donated to existential risk reduction) exceeds the expected harm, then you have a framework with no principled constraints. [[Émile Torres]] and others have argued that MacAskill's longtermism inherently produces this moral hazard. The framework doesn't forbid such outcomes — it merely treats them as tragic tradeoffs within expected value calculation. ### The Earning to Give Critique Critics argue that "earning to give" as MacAskill articulated it contains several embedded pathologies: 1. **Moral hazard**: It removes ordinary ethical constraints on how you earn money, creating incentives toward fraud and corner-cutting 2. **Selection effects**: It attracts people motivated primarily by wealth accumulation who use EA as moral camouflage 3. **Corruption of purpose**: It transforms charitable giving into a justification for extractive economic behavior ### The Torres-Gebru Critique [[Émile Torres]] and [[Timnit Gebru]] have argued that effective altruism, and longtermism specifically, functions as moral legitimacy for the tech oligarchy. The argument: - Tech billionaires want to direct massive resources toward causes they find intellectually interesting (AI safety, space colonization, etc.) - Longtermism provides a moral vocabulary that makes this self-interested resource allocation sound like saving civilization - EA institutions provide the infrastructure for this legitimacy transfer - This serves the oligarchy's interests while cloaking them in utilitarian morality ### The Democratic Accountability Gap Who decided that AI safety is more important than malaria prevention? Who decided that the long-term trajectory of civilization should take priority over measurable present-day suffering? The answer is: MacAskill, through a combination of philosophical arguments and institutional control. But he was not elected, appointed by any legitimate authority, or subjected to any democratic accountability mechanism. The concentration of resource allocation decisions in the hands of one charismatic philosopher with institutional control over billions of dollars represents a form of unaccountable power. This power is particularly troubling because it derives from persuasiveness (philosophical and rhetorical) rather than democratic legitimacy. ### The Philosopher-King Problem MacAskill embodies what philosophers call the "philosopher-king problem." Plato argued that those who understand moral truth should rule society. MacAskill has constructed a scenario where this occurs: a philosopher who controls the institutional apparatus directing billions of dollars toward causes he finds morally compelling. The problem: philosophers disagree about moral truth. MacAskill's longtermism is a contested philosophical view. His institutional control over EA's resource allocation means that one contested philosophical view determines funding priorities that shape the work of thousands of people. This is not democratic. It is not accountable. It is rule by unelected philosopher. ## Connections to Right-Wing Power Structures MacAskill's work serves the interests of tech oligarchy in multiple ways: 1. **Moral legitimacy**: Longtermism provides tech billionaires with moral justification for their philanthropic priorities 2. **Network integration**: EA brings together tech billionaires, libertarian-leaning intellectuals, and utilitarians into a unified ideological framework 3. **Avoidance of redistribution**: Longtermism, by focusing on speculative long-term causes, avoids the redistributive implications of utilitarian ethics. It allows billionaires to feel they are helping humanity without engaging in wealth redistribution 4. **Preservation of meritocratic mythology**: EA's emphasis on evidence, reasoning, and merit-based allocation serves to legitimize market-based inequality as reflecting genuine differences in talent and moral value MacAskill is thus a crucial figure in [[The Unholy Alliance]] — the synthesis of tech oligarchy and philosophical movement that provides moral legitimacy to concentrated wealth and power. ## See Also - [[Effective Altruism]] - [[Longtermism]] - [[TESCREAL]] - [[Sam Bankman-Fried]] - [[Nick Bostrom]] - [[Peter Singer]] - [[Émile Torres]] - [[Timnit Gebru]] - [[80,000 Hours]] - [[Giving What We Can]] - [[Centre for Effective Altruism]] - [[Global Priorities Institute]] - [[The Unholy Alliance]] - [[FTX Collapse]] - [[Toby Ord]] - [[Hilary Greaves]] ## References and Further Reading - MacAskill, W.
