The meat of this paper is applying the "person-affecting stance" to the question of timing. There's a lot of philosophy background in that phrase, but the paper describes the key distinction well on page 4:

> In particular, we may distinguish between a person-affecting perspective, which focuses on the interests of existing people, and an impersonal perspective, which extends consideration to all possible future generations that may or may not come into existence depending on our choices.

In philosophy, it's always fine to see where ideas lead. For the rest of us, though, we might take pause here because the "person-affecting" perspective is insane in this context. It gives full moral weight to whether you make things better or worse for people who happen to be alive right now -- but no moral weight at all to whether you leave a world that's better or worse for people who will be born any time after right now. Wanna destroy the biosphere or economy in a way that only really catches up to tomorrow's kids? Totally fine from the "person-affecting perspective", because in some technical sense, no individual was made worse off than they were before. They were born into the mess, so it's not a problem.
