Could be. I honestly don't know. I didn't even consciously remember Key baking cupcakes by the time the story ended and I asked myself what might have influenced me.
I also had the feeling that the story wasn't really about Key; ey just serves as an expository device. Ey has no unpredictable or even unusual reactions to anything that would establish individuality. The setting should then draw the most interest, and it didn't do enough that, because it was too vague. What is the government? How does it decide and enforce allowed research, and allowed self-modification? How does sex-choosing work? What is the society like? Is Key forced at a certain age to be in some regime, like our schools? If not, are there any limits on what Key or her parents do with her life?
As it is, the story presented a very few loosely connected facts about Key's world, and that lack of detail is one reason why these facts weren't interesting: I can easily imagine some world with those properties.
What is the government?
Small communities, mostly physically isolated from each other, but informationally connected and centrally administered. Basically meritocratic in structure - pass enough of the tests and you can work for the gubmint.
How does it decide and enforce allowed research, and allowed self-modification?
Virtually all sophisticated equipment is communally owned and equipped with government-designed protocols. Key goes to the library for eir computer time because ey doesn't have anything more sophisticated than a toaster in eir house. ...
ITT we talk about whatever.
