Oldie but goodie. A piece of fiction describing how a computer system can do the job of human managers at fast food restaurants (scarily plausible), how this leads to a dystopia (slowly getting implausible), and how to avoid this scenario and reach utopia (give me a break).
Manna is a fun story.
The bit where the machines control the humans reminds me of my Automating body and mind video. I actually cite Marshall Brain in that one, two and a half minutes in.
