Genetic and epigenetic changes that allowed more humans to survive some diseases, at the cost of future problems. We inherited all the kludge that allowed our ancestors to survive different conditions, and it gave us a huge technical debt. Which just makes the comparison *chef's kiss*.

I wouldn't stretch the software analogy further given the weird history but yeah it makes sense
