What We Owe the Future is a 2022 book by the Scottish philosopher and ethicistWilliam MacAskill, an associate professor in philosophy at theUniversity of Oxford. It advocates foreffective altruism and the philosophy oflongtermism, which MacAskill defines as "the idea that positively influencing the long-term future is a key moral priority of our time."[1]: 4 His argument is based on the premises that future people count, there could be many of them, and we can make their lives better.[2]
MacAskill makes the case forlongtermism—an ethical stance which gives priority to improving the long-term future—and proposes that we can make the future better in two ways: "by avertingpermanent catastrophes, thereby ensuring civilisation's survival; or by changing civilisation's trajectory to make it better while it lasts ... Broadly, ensuring survival increases the quantity of future life; trajectory changes increase its quality".[1]: 35–36 According to MacAskill, the present era is a critical juncture: "Few people who ever live will have as much power to positively influence the future as we do. Such rapid technological, social, and environmental change means that we have more opportunity to affect when and how the most important of these changes occur".[1]: 39
His argument for longtermism has three premises: first, future people count morally as much as the people alive today; second, the future is immensely big since humanity may survive for a very long time, and there may be many more people alive at any given time; and third, the future could be very good or very bad, and our actions may affect what it will be.
To improve the future, MacAskill investigates how moral change and value lock-in may constitute long-runtrajectory changes for civilisation. He suggests that moral and cultural values are malleable, contingent, and potentially long-lived—if history were to be rerun, the dominant global values may be very different from those in our world; for example, the abolition of slavery may not have been morally or economically inevitable.[1]: 70 MacAskill warns of a potentialvalue lock-in—"an event that causes a single value system ... to persist for an extremely long time"[1]: 78 —which he believes may result from technological advances, particularly the development ofartificial general intelligence.[1]: 80–86
Next, MacAskill explores how to protect humanity from risks ofextinction,unrecoverablecivilisational collapse, and long-runtechnologicalstagnation. He argues that the most severe threats of human extinction are posed byengineered pathogens andmisaligned artificial general intelligence. He also discusses several potential causes of civilisational collapse—including extremeclimate change,fossil fuel depletion, andnuclear winter caused bynuclear war—concluding that civilisation appears very resilient, with recovery after a collapse being likely.[1]: 127–142 MacAskill next turns to risks of long-lasting technological and economic stagnation. While he considers indefinite stagnation unlikely, "it seems entirely plausible that we could stagnate for hundreds or thousands of years".[1]: 144 From a longtermist perspective, this matters primarily because long-term stagnation makes extinction or collapse more likely, and because the society emerging after the period of stagnation may be guided by worse values than society today.[1]: 142, 144
The book also discusses how bad the end of humanity would be, which depends on whether the future will be good or bad in expectation and on whether it is morally good for happy people to be born—a key question inpopulation ethics. He concludes optimistically that the future will likely be positive on balance, in part because future people are asymmetrically motivated to bring about good things rather than bad things.[1]: 218 He also claims that preventing future people from coming into existence is a moral loss if their lives would be sufficiently good, leading him to conclude that "the early extinction of the human race would be a truly enormous tragedy".[1]: 189, 193
The book's final part details how to choose which problems to focus on, along with what people can do to take action. In areas such as climate change, fossil fuel depletion,biosecurity,pandemic preparedness, anddisaster preparedness, people can take "robustly good actions" like research and advocacy to help.[1]: 291 Meanwhile, for issues with more unknowns, such as reducingAGI risk and preventing great-powerwars, building up options and learning should be prioritized.[1]: 292–294
For the individual, MacAskill emphasises the significance of professional work, writing that "by far the most important decision you will make, in terms of your lifetime impact, is your choice of career".[1]: 234 He mentions80,000 Hours, a nonprofit he helped co-found, which conducts research and provides advice on which careers have the largest positive impact, especially from a longtermist perspective.[3][4] He also argues that donations to effective longtermist causes and organisations are much more impactful than changing our personal consumption.[1]: 232
What We Owe the Future has received coverage inThe New Yorker,[5]NPR,[6]The Ezra Klein Show,[7]The Bookseller,[8] andNew York Magazine.[9] Adaptations of the book's central thesis have been published by MacAskill inForeign Affairs,[10]The New York Times,[11] and theBBC.[12]
Publishers Weekly's review described the book positively: "MacAskill delivers a sweeping analysis of contemporary dangers that masterfully probes the intersections of technology, science, and politics, while offering fascinating glimpses into humanity's possible futures. This urgent call to action will inspire and unnerve in equal measure."[13]Kirkus Reviews's review was also favorable: "With something to ponder on every page, a bracing exhortation to do right by the people of centuries to come."[14]Kieran Setiya writes in theBoston Review that it "is an instructive, intelligent book ... But a moral arithmetic is only as good as its axioms. I hope readers approach longtermism with the open-mindedness and moral judgment MacAskill wants us to preserve."[15] Writing forThe Guardian,Oliver Burkeman reviewed the book very favorably, calling it "the most inspiring book on 'ethical living' I've ever read."[16]
What We Owe The Future, and the effective altruism movement more broadly, were reported on in a cover story forTIME Magazine by Naina Bajekal, who writes "all the lives still to come ... could be so much better and richer in meaning—or so much worse. If that depends on what we all do in the next few decades, I don't know exactly how to help ensure our actions are for the better. But if the future could be as vast and good as MacAskill thinks, it seems worth trying."[17]
In a critique of the so-called "quasi-religious worldview of longtermism",Salon gave a negative review of the book: "One must wonder, when MacAskill implicitly asks 'What do we owe the future?'whose future he's talking about. The future of indigenous peoples? The future of the world's nearly 2 billion Muslims? The future of theGlobal South?"[18] Barton Swaim's review forThe Wall Street Journal was also negative: "Rarely have I read a book by a reputedly important intellectual more replete with highfalutin truisms, cockamamie analogies and complex discussions leading nowhere. Never mind what we owe the future; what does an author owe his readers? In this case, an apology."[19]
What We Owe the Future was first published in the United States byBasic Books in August 2022,[20] along with an audiobook version, narrated by William MacAskill and published byRecorded Books.[21] An edition, with the subtitle "A Million-Year View", was published in the United Kingdom byOneworld Publications in September of the same year.[22]
