An automaton seems too similar to a zombie to give the "diverse mix of things" impression a "from A to Z" title should give off. I'd think the book was about mindlessness, and presumably how rational people can avoid behaving like the mindless automata and zombies that make up the common rabble, which isn't exactly how I would characterise the sequences, even if EY does sometimes talk about being a PC instead of an NPC.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
