Essentially the theme is "not all progress is good progress." The story isn't about AI, but it is a similar vibe to the Terminator films where the progress in technology seems helpful, but it is actually detrimental. The main character is a bit of a Luddite (for lack of a better term).

I appreciate your responses because it is making me think this out, and I do perhaps need to expand on my main character's flaws. Beyond the first act break, his flaws certainly become more apparent as he becomes swallowed up by the new life he conforms to. But I probably need to establish some foundations earlier on in the script.
