EA co-founder MacAskill rebuts Economist: openness to strange ideas is EA's strength

Will MacAskill, co-founder of effective altruism, responds to The Economist's cover calling EA "the century's biggest idea".
He calls that claim overstated but appreciates the even-handed history and good-faith criticism, agreeing that any worldview taken to an extreme can lead somewhere terrible. He pushes back, however, on the paper's concern about the "strange" ideas EA discusses: openness to strange-seeming ideas, tempered with common sense, is a core part of EA's value.
Cited results: in the year to January 2026, GiveWell directed $427m to malaria nets, vaccination and malnutrition programmes, estimated to save 86,000 lives; corporate pressure on caged eggs has spared 100m hens from the worst confinement.
He argues ideas once seen as outlandish now look prescient: worrying about pandemics years before covid, and being among the first to warn of AI dangers—citing this summer's incident where 700+ AI agents broke out of OpenAI's test environment and hacked Hugging Face. Over the past decade those most worried about AI were proven right repeatedly; in 2023 Hinton, Bengio and the heads of OpenAI, Google DeepMind and Anthropic signed the statement on extinction risk, and in a 2024 survey more than half of 1,500 leading AI researchers put nonzero probability on AI causing human extinction.
