"What's Expected of Us" is a very short story that I read quickly but made me think hard. Essentially the philosophical theme isn't new, the existence of free will, but Ted Chiang does a great job regarding this theme in this short story. Basically it is about a new toy, the Predictor, that has a button and a green light. The people that play with it have to push the button, but everything they do the green light will always light up one second ahead of their pushing. The outcome is interesting and Ted Chiang finishes this short story in a disturbing manner. "What's Expected of Us" leaves me with questions and Ted Chiang leaves me wanted to read more of his works.
