Scientist have already pulled together giant “population-scale” trees based on genealogy data from Geni.com that seemingly are structurally sound.
An article came out in 2018 about this. I wonder how much progress has been made in the last 4 years. The old article behind a firewall is at https://science.sciencemag.org/content/360/6385/171
It would seem that adding DNA to the bottom layers of a genealogy tree like the above would be doable with a decent AI team. Clustering is a trivial tool yet it can ferret out common ancestors already. Imagine having all 20 million peoples DNA data available with giant trees at the same time. Once validated, maintenance could be performed by just adding oneself to the tree.
The world tree at Geni.com already allows users to import haplogroup data from FTDNA and it is populated up the tree for 10 generations.
Rumors have it that scientist in the “back room” at MyHeritage (owners of Geni) and Ancestry.com are already working on a giant world tree. But it is as politically sensitive as using CRISPR on living humans. And they haven’t figured out yet how to monetize it.
I am patiently waiting and adding my well sourced genealogy data to every tree I can, and am doing DNA tests at every company too. And hoping….
