A demo-bot just tore through Lanning's house—with me still inside. Dr. Susan Calvin: That's impossible. Detective Del Spooner: [sarcastically] Yeah, I'll say it is. [truthfully] Do you know anything about the "ghost in the machine"? Dr. Susan Calvin: It's a phrase from Lanning's work on the Three Laws. He postulated that cognitive simalactra might one day approximate component models of the psyche. [Del looks confused] Oh, he suggested that robots could naturally evolve."
