I can relate to this idea. IMO ee have a bias towards the future and tend to think of the destruction of something as erasing all the value it ever had. But if you think of all of spacetime rather than your specific point in it, any life that's ended compared to those still ongoing is exactly as real and has as much "value", which isn't lost. Considering a completely different meaning of "loss", there's certainly benefit to the constant renewing of the world by death and birth, but there's still a very real loss in our best and brightest growing old and dying (mainly due to the former), because of their lost experiences (hence skills, etc). If everyone lived half as long but the birth rate doubled surely the world would be a far worse place. So I do think "it is useful to think of it as a loss." Thanks for discussing, regardless of some people apparently being displeased.
