1. In this film, it seems that boss is the only one who is benefited by the technology. He used cameras to spy Charlie and manage his company, he used machinery for mass production, and he use that feeding machine to cut the lunchtime! Everything that the boss did, is to push every workers to the limit, and push his profit to the limit, this is the benefit for the boss.
2. It also seems that the technology is causing a great trouble for Charlie, but not for his boss. Charlie's mind is twisted by the machine, he can't stop working, and he even "work" the other strangers, causing trouble to the others. And for his body, he is harmed by the "feeding machine"! And for his life, beside he gone mad because of the machinery, his life is also being "watched" by his boss.
3. I agree that technology really change our mind/ habit, for Charlie, he can't stop working. For me, my computer has changed me, I will turn on my computer unconsciously when I get home. My life is really filled by technology (for example: forum, youtube, mp3. internet, facebook...etc), but I think it is ok, as I think that I still got my real life, and not totally controlled by my computer.
It seems that other classmates agree what I think about this film. And they think that technology can give them a more convenient life, I agree with this idea too, for example, comparing writing and typing, it is obvious that typing is way faster then writing, comparing horse cart and car, comparing email and snail mail, technology always win, and technology always makes our life become more convenient.
