Collapse is evident in that almost nothing survives being immortal except cancers and flatworms. You witness the evidence of this "collapse" all around you in that virtually nothing deigns to live forever and tell the tale (genetically speaking), and then you call me neglectful of some evidence?
And as for your challenge, you don't know the conversations I've had with people I love. The politics of immortality are so challenging that I prefer not to write my sincere beliefs on the public internet.
EDIT: I do appreciate the chance to engage with ppl so different from the sort I regularly speak with, and so am grateful for the words, even if it seems we are both a little frustrated by them. Which is to say, thanks
