Hi Graham,

thanks, I’m blown away by the breadth of this argument, and the finite list assumption on strong upper bound ‘wipe-out’ events of humanity’s existence make sense. I need to think a bit more on exactly what kind of mathematical argument is this, seems familiar from analysis, some middle value kind of argument maintaining existence but not showing unicity of an opportunity, but am running ahead of myself.

However, my question is really framed with an individual human being in mind, and assumes a technology that eliminates all internal aging-related (very distal and not proxy) causes of death and assumes only non-zero chance of dying every day (every minute, every second,…) from external causes.
