I have a friend in London who's at war with her car's GPS. Although she nearly always puts it on, she's driven mad by its voice, which is female, and refuses to follow its directions. She spends whole trips arguing with, barking at, and sometimes cursing this imaginary woman. She'd never be this rude to an actual human being. But, of course, a GPS doesn't have feelings.
But what if it did? That's one of the many timely questions raised by Westworld, the darkly exciting new series that's HBO's biggest gamble since Game of Thrones.
