text: Several works use AI to force us to confront the fundamental question of what makes us human, showing 
  us artificial beings that have the ability to feel, and thus to suffer. This appears in Karel Čapek's*R.U.R.*, 
  the films*A.I. Artificial Intelligence*and*Ex Machina*, as well as the novel*Do Androids Dream of Electric*
  *Sheep?*, by Philip K. Dick. Dick considers the idea that our understanding of human subjectivity is altered 
  by technology created with artificial intelligence.[404]
