Yeah, but on the other hand if you have a sibling - by this logic - it would be counted as another 4096 additional “past people” but it isn’t. And because in the past families were quite larger, having 10-15 kids, I wonder how much finding and substracting those doubles would shrink the “billion trillion” ancestors number
But that math equation (doubling every time) is just for one person to exist. It’s not making any assumptions about shared ancestry or the current population vs the ancestry population
