She exists in a quantum state, simultaneously both childlike & needing protection and a fully-grown adult with relatable job problems, depending on the story he wants to tell.
Just like how almost all QC's AI have slowly morphed from entertaining and interesting "goofy little chaos bastard"-style AnthroPCs into pastel humans who are simultaneously oppressed daily & denied basic civil rights, but also qUiRKy weirdos with a near-suicidal lack of common sense who basically have to be babysat by the humans.
Jeph isn't interested in consistency, he just wants to tell the stories that interest him. That means sometimes the AI stuff is treated seriously and sometimes it's played extremely opposite for laughs. And I don't even necessarily begrudge him that: you've gotta write what you care about or you'll burn out fast. But it does make reading the comic confusing and makes it hard to maintain immersion if you're the kind of reader (I know I am) who needs consistent characterization.
