Even more remarkable is that by the estimate in Table 1, the percentage is increasing over time.

If this trend continues over the centuries it is conceivable that >=50% of all human beings to ever exist could be extantly alive. Either growth rate exploded or death rate arrested.

It recalls to mind Fyodor the one-time teacher of Tsiolkovsky of the rocket equation, who conceived a kind of akashic immortality project he called the Common Task. So like maybe this Kaneda-Haub statistic asymptotically approaches 100%.

Supposing a starting population of 2 we can call Adam and Eve divided by 0 dead ancestors do note it started at infinity before dropping precipitously near 0 for a 202k year exponential climb to today's ~7%. Fwiw I consider such plot affirmative evidence assuming the demographic inputs are not wildly inaccurate.
