What We Owe The Future is a 2022 book by William MacAskill, a philosopher and leading figure in the effective altruism movement. The book argues for long-termism, the idea that positively influencing the long-term future is a key moral priority of our time.
I guess this is some long termism stuff. It's kind of like a Will McCascal Pel type approach to things.
""The speaker refers to 'Will McCascal Pel type approach to things,' which is a clear reference to William MacAskill and his work on long-termism, with 'What We Owe The Future' being his most prominent book on the topic."
