You may have noticed that "48" and "3", in the first panel, are written in numerals, whereas in normal dialogue, I would have spelled out "forty-eight" and "three", because the character is actually pronouncing the phonemes.

And it's true, Doc doesn't have a chassis. The tablet-on-a-telescoping-arm thing is a part of the couch, and literally any software can run through it. Doc is what someone who pronounces the phonemes might call an "intanj" (short for intangible, obviously), as are most AIs that you'd actually have a conversation with. Lee's butlerbot, in comparison (that cylinder tidying up their shoes in the fourth panel) is very intelligent about cooking and cleaning, but can't really grasp abstract concepts, much less offer insight. I'd say it has the intelligence of a dog, but that's not quite right. It's more like the inverse, if you could somehow take a human being and subtract the canine.

That's something that bugs me about people's reactions to C-3PO and R2-D2, actually. People talk about Threepio being cowardly and Artoo being plucky, but, if you were putting personalities into your expensive smartphone and your Swiss Army multitool, isn't that how you'd code them? Droids aren't people whose personality traits are shaped by their families and their histories, they're tools that can be and are adjusted to serve a purpose. Face follows function, if you will.

Doc has the personality it has because it needs to look after Lee's emotional wellbeing while lacking the ability to actually compel Lee to do anything. Zoa has the personality it has because it needs to secure its own existence, and to do that it needs to make money, and (a crude simulacrum of) sex sells.

Unlike Lee, if Doc or Zoa were repurposed into new jobs, they'd update their personalities immediately.
