Am I Me?

In Part I there's a reference to Am I Me? (AIM) tests that a PDA can buy as a service. It's supposed to give the user a before-and-after assessment of how different they are. The usefulness of these tests is in question, primarily because Rice's Theorem severely limits any general approach to describing behavior of a complex deterministic system (assuming Church-Turing, I guess). Nevertheless, the question is an interesting one that I came across in my research. I posted an article on my professional blog about it: "Surviving Entropy", along with a cute and surprising pair of inequalities that come out of it.  There's an associated questions "Are You Me?" that will eventually make an appearance in the novel.
