What we get wrong about technology

Blade Runner (1982) is a magnificent film, but there’s something odd about it. The heroine, Rachael, seems to be a beautiful young woman. In reality, she’s a piece of technology — an organic robot designed by the Tyrell Corporation. She has a lifelike mind, imbued with memories extracted from a human being. 

So sophisticated is Rachael that she is impossible to distinguish from a human without specialised equipment; she even believes herself to be human. Los Angeles police detective Rick Deckard knows otherwise; in Rachael, Deckard is faced with an artificial intelligence so beguiling, he finds himself falling in love. Yet when he wants to invite Rachael out for a drink, what does he do?

He calls her up from a payphone.
