I know I'm way behind in listening, so it's as likely as not that no one will ever read this post.
I thought the story was well written, that is the prose was well crafted, but at the same time, the ultimate themes were entirely banal. What I came away with is that marketing is evil and preys on vulnerable people and its sad and lonely to be fat. On the one hand, that's fine. You can't get big ideas from every story and for a YA story these ideas might have been fine.
But on the other hand, what made them stand out in stark relief as weak tea, was that there were some really big ideas here that the author either didn't see or willfully chose to ignore.
There is some serious, serious deep stuff here about the meaning and purpose of life and the nature of free will.
If one were teaching this story on a YA level, one might ask the class about the nature of marketing, and whether or not it would be ethical to create a snack cake with the ability to subvert someone's will, and how does that relate to marketing and advertising today.
But one could teach this story on a college level philosophy class and start out by asking, what is different between Linda and the snack cake? Why are we sad when Linda dies, and not when Smidgen does? Smidgen is sentient (or at least believes he is -- is the ability to construct a narrative about oneself proof of sentience?) Does Smidgen have free will? Does Linda have free will, given what we are able to observe about her? Is her free will limited? Is her suicide an example of the Nietzschean will-to-power, that is, even more than self-preservation, the ultimate driver of human action is a desire to control? How can Smidgen be so motivated to die, knowing that there can be no concrete pleasure in it for him, as his sentience will no longer exist? He wants to die as well, but in his case, it doesn't seem to be an act of will. He apparently longs for it with ecstatic, almost erotic passion. Can he really be free willed and sentient if he seeks fulfillment in death, absent any belief in an afterlife? Would it be ethical to create sentient beings who believed there only fulfillment and purpose was to die for us? Are we gods at that point? Is that our role with our creator?
Sadly, I don't think the author really considered what he had created here. There aren't any clues in the story that the author really thought hard about these things. While its not fair to complain that a story isn't what you wanted it to be, I wish this story had been a little bit more Phillip K. Dick and a little less cute.
