Re: What will replace the robots
"robot" derives from "robotnik", the Polish word for "worker"...
erm, it does not. It was used first by a Czech writer (Karl Capek?), around 1920s, so if anything, it would be taken from Czech. Although it probably does have a relation to the Czech version of "robotnik", which is, if I remember right, also used in Russian, in various forms.
actually thus speaks wikipedia:
R.U.R. is a 1920 science fiction play in the Czech language by Karel Čapek. R.U.R. stands for Rosumovi Univerzální Roboti.
ah, never mind!
