This is pretty tangential, but it’s interesting to me that the examples use Mises, Hayek, and Menger. These are three famous economists that of which Menger is a shared ancestor in the other two’s academic-advisor-genealogy. In academic advisor genealogy being a direct descendant of one academic advisor just means that you had them as an advisor, thus since an advisor has multiple Ph.D. students It creates a family tree like structure. Anyways, I only learned this, because my Dad is actually an academic advisor descendant of Mises and Menger. Anyways if there is any Ph.D.s lurking here on hacker news in a mathematical field you might be able to find your own advisor genealogy here: https://www.genealogy.math.ndsu.nodak.edu/id.php?id=200008
