Respectfully: You do. You must. Or if you don't, then life misunderstands itself. For life has adopted this pattern of death in essentially every conceivable domain, every ecological niche. Further, any hypothesised lifeform that has discovered death as unnecessary, they curiously have not arrived here for us to interrogate. The significance of that seems vaguely familiar, but perhaps just Fermi ;)
You don't know me, but I usually air toward speaking humbly about things I suspect I know. Readers are free to decide which perspective is true hubris: my hubris that aligns with all known living systems and their failed aspirations of immortality, or the other hubris that stands alone with cancers and brainless jellies, where death is a failure of all historical life to discover otherwise... that the cleverness of life we laud so much praise on -- the same life which has invented every enchanted bit of protein machinery that runs this whole beautiful mess -- that it has somehow had a blind spot all these millennia, that we humans have seen clear-eyed.
Death is hegemonic for a reason. It's the Chesterton's fence around the whole damn bustling city, that we've never seen what comes from the other side of, if we finally remove it.
Much love here. I don't mean to be dismissive, this is just something I care about deeply and wish to speak firmly on.
