Here's my basic analysis
Tempbot can't relate ot the personal world, and so his attempts to fit in fail. They condemn him when he can't, but ironically they create more and more of an impersonal world of 'people' like tempbot in the end anyway. Tempbot represents the alienated person isolated from real relationship (he can't even talk). So what do they do? They end up creating an even more alienated world of others like him in the end. The other bots have replaced the workers, or metaphorically, the workers have become impersonal bots. Tempbot has given up the desire for love, having torn the picture of him and the woman in half. But he is happy because he now fits in.
Basically I think the film is about alienation and being a misfit, and how society/work just creates more people like that.
