Should our priorities change when we consider all the lives yet to come?

The challenges we face are enormous. But we can still secure a positive future for our planet, and for everyone on it.

In What We Owe The Future, philosopher William MacAskill persuasively argues for longtermism, the idea that positively influencing the distant future is a moral priority of our time. It isn't enough to mitigate climate change or avert the next pandemic. We can ensure that civilization would rebound if it collapsed; cultivate value pluralism; and prepare for a planet where the most sophisticated beings are digital and not human.
