The word "robot" originated in the 1920 Czech play "R.U.R." (Rossum's Universal Robots) by Karel Čapek. Derived from the Slavic word "robota," meaning forced labor or servitude, the term originally referred to synthetic humanoid workers. The play's plot, involving a robot uprising that slaughters humanity, established the "looming threat" trope that persists in modern AI discussions.
