Ah, I see what you mean, but if you contrast "automatic differentiation" and "algorithmic differentiation" with each other, it's counterintuitive to me that these terms should be "oriented" differently. Either I imagine that the differentiation is automated or algorithmized, or I could imagine that it's an automaton or algorithm being differentiated. But it's confusing to me if it's algorithm being differentiated vs. differentiation being automated. Not sure if that explains sufficiently clearly what confused me.
