I found this engaging and also deeply editorial. As someone who identifies as "not sure" about life after death, I wouldn't agree that I'm a "fence sitter." Nor do I feel that  ". . .  we're cursed to never know what's on the other side [of death]."  Not knowing what happens after we die is not, in my opinion or experience, a curse. That vibe contributes to death anxiety and diminishes an exploratory curiosity. (Edited to add since religious affiliation is part of the study: I'm a life-long religiously active person and an ordained clergy person.)

Chang wrote up a behind-the-scenes on this visualization.

While by no means, The Answer, since it has helped me think about how to be a better human in the present, I've likened the afterlife to a tree that falls in the forest and decays, giving its life back to other organisms and the next generation.

You physically die, but your interactions, your kindnesses (and unkindnesses) and shared ideas, are carried forward by those you influenced to be passed along to the next generation. A variation of objective immortality. 

I almost died and went through "the tunnel" to the light.  Then I regained consciousness.  It helped me feel confidently that there is more to life than our time on earth in physical bodies.  I definitely think who or whatever we are lives on in some unknowable way (unknowable while we are constrained to the physical) after our bodies die.  There's too much evidence for it, too many experiences and now that I've had my own brief glimpse, I feel like it is more than say, imaginary projection.  There's more.  We don't know what or why and that is why humility is a core tenet of human knowledge, or should be.
