What if I can't just "try" it? What if the machine can only be used once? Or (my preference) if some deep "brain sex" transformation only works once, even if a more superficial motor remapping is easy to do or re-do? Come up with whatever frame story you want for this: maybe the machine costs my life savings just to rent for two minutes, or maybe the transformation process is ever-so-slightly imperfect, such that you can't re-transform someone who's already been transformed once, like a photocopy being a perfectly acceptable substitute for an original document, but photocopies-of-photocopies rapidly losing quality.
-In that case, if I have to choose ... I _don't_ think I want to be Actually Female? I _like_ who I am on the inside, and don't need to change it. I don't _want_ to stop loving challenges and points—or women!—in the way that I do. And if I don't know enough neuroscience to have an _informed_ preference about the ratio of gray to white matter in my posterior lateral orbitofrontal cortex, I'm sure it's _probably fine_.

At the same time, the idea of having a female body still seems like _the most appealing thing in the world_. If artificial superintelligence gives me BodyApp to play with for a subjective year and [tiles the _rest_ of our future lightcone with paperclips](https://www.lesswrong.com/tag/paperclip-maximizer), that's _fine_; I will die _happy_.
(I guess I can't evade responsibility for the fact that I am, in fact, blogging about this.)
-A clue: when I'm masturbating, and imagining all the forms I would take if the magical transformation technology were real (the frame story can vary, but the basic idea is always the same), I don't think I'm very _good_ at first-person visualization? The _content_ of the fantasy is about _me_ being a woman (I mean, having a woman's body), but the associated mental imagery mostly isn't the first-person perspective I would actually experience if the fantasy were real; I think I'm mostly imagining a specific woman (which one, varies a lot) as from the outside, admiring her face, and her voice, and her breasts, but somehow wanting the soul behind those eyes to be _me_. Wanting _my_ body to be shaped like _that_, to be in control of that avatar of beauty—not even to _do_ anything overtly "sexy" in particular, but just to exist like that.

If the magical transformation technology were real, I would want a full-length mirror. (And in the real world, I would probably crossdress a _lot_ more often, if I could pass to myself in the mirror. My face ruins it and makeup doesn't help.)
I now realize that the correct answer to [the question](https://www.lesswrong.com/posts/vjmw8tW6wZAtNJMKo/which-parts-are-me) is—_yes!_ Yes, it's cheating! Category-membership claims of the form "X is a Y" [represent hidden probabilistic inferences](https://www.lesswrong.com/posts/3nxs2WYDGzJbzcLMp/words-as-hidden-inferences); inferring that entity X is a member of category Y means [using observations about X to decide to use knowledge about members of Y to make predictions about features of X that you haven't observed yet](https://www.lesswrong.com/posts/gDWvLicHhcMfGmwaK/conditional-independence-and-naive-bayes). But this AI trick can only _work_ if the entities you've assigned to category Y are _actually_ similar in the real world—if they form a tight cluster in configuration space, such that using the center of the cluster to make predictions about unobserved features gets you _close_ to the right answer, on average.
-The rules don't change when the entity X happens to be "my female analogue" and the category Y happens to be "me". The ordinary concept of "personal identity" tracks how the high-level features of individual human organisms are stable over time. You're going to want to model me-on-Monday and me-on-Thursday as "the same" person even if my Thursday-self woke up on the wrong side of bed and has three whole days of new memories. When interacting with my Thursday-self, you're going to be using your existing mental model of me, plus a diff for "He's grumpy" and "Haven't seen him in three days"—but that's a _very small_ diff, compared to the diff between me and some other specific person you know, or the diff between me and a generic human who you don't know.

In everyday life, we're almost never in doubt as to which entities we want to consider "the same" person (like me-on-Monday and me-on-Thursday), but we can concoct science-fictional thought experiments that force [the Sorites problem](https://plato.stanford.edu/entries/sorites-paradox/) to come up. What if you could _interpolate_ between two people—construct a human with a personality "in between" yours and mine, that had both or some fraction of each of our memories? (You know, like [Tuvix](https://memory-alpha.fandom.com/wiki/Tuvix_(episode)).) At what point on the spectrum would that person be me, or you, or both, or neither? (Derek Parfit has [a book](https://en.wikipedia.org/wiki/Reasons_and_Persons#Personal_identity) with lots of these.)
