Science-fiction novels and films have long popularized the notion that 
machines will, sooner or later, match and ultimately
                     exceed human-level intelligence. On the way they 
will acquire feelings and consciousness. In the most famous such movie, Blade Runner, a replicant exclaims in the face of its imminent demise, 
"I've seen things you people wouldn't believe. Attack ships on
                     fire off the shoulder of Orion. I watched c-beams 
glitter in the dark near the Tannhäuser Gate. All those moments will be
                     lost in time, like tears in rain. Time to die."
—revealing in its eloquence and poignancy its (simulated) humanity.
