R.U.R.

I don't remember where I first heard of this (probably in one of my books about 1920/the 20s), but once I read that it's where the term “robot” came from, I had to read it. I didn't realize it was a play!

This was really good and I'm surprised it hasn't really been adapted yet (it has adaptations, but nothing big) as it has so many elements that are popular - the creation of the robots, the over reliance on them, their uprising, the last man trying to save it all... What a story.
