What is longtermism according to William MacAskill?

Longtermism posits that positively influencing the distant future is a moral imperative. MacAskill argues that future generations could vastly outnumber us, so reducing existential risks and improving civilizational trajectories today could benefit trillions of potential lives.

What existential risks does the book highlight?

Key risks include:

• Catastrophic climate change
• Unregulated AI development
• Pandemics and bioweapons
• Civilizational collapse without recovery mechanisms
• Moral backsliding halting societal progress

How does MacAskill justify prioritizing future generations?

Using population ethics, he asserts that future lives are equally valuable to current ones. Historical examples—like ending slavery—illustrate how moral shifts can have long-lasting positive ripple effects, justifying proactive investments in humanity’s future.

What is "moral entrepreneurship" in the book?

Moral entrepreneurship refers to pioneering ethical innovations that reshape societal values. MacAskill cites movements like abolitionism and environmentalism as examples, urging readers to champion new norms that benefit future societies.

How does the book address digital minds?

MacAskill warns that AI-driven digital consciousness could dominate the future, potentially outpacing human intelligence. He stresses the need to align these minds with humane values to prevent dystopian outcomes.

What practical steps does MacAskill recommend?

• Preserve resources (e.g., leaving coal reserves for post-collapse energy)
• Promote moral resilience to prevent backsliding
• Invest in AI safety research
• Reduce extinction risks through global cooperation

What are common critiques of What We Owe The Future?

Some Effective Altruists argue it overemphasizes speculative risks while undervaluing near-term interventions. Others question whether longtermism neglects present-day marginalized communities, though MacAskill addresses these tensions in later chapters.

How does the book use historical examples?

It draws parallels like 19th-century abolitionism to show how minority viewpoints can drive moral progress. The Glyptodon extinction illustrates irreversible consequences of short-term thinking, while coal’s role in post-collapse recovery underscores strategic resource preservation.

How does What We Owe The Future compare to MacAskill’s earlier work?

While his prior books focus on Effective Altruism’s principles, this title scales those ideas to a civilizational level, integrating philosophy with futurology. It’s broader in scope but retains his trademark blend of academic rigor and pragmatic optimism.
