What Westworld gets wrong (and right) about human nature

A central theme of HBO's new sci-fi series "Westworld" is the question of what it means to be human. The setting is an immersive adult theme park that's been fashioned after the American Old West and is inhabited by intelligent lifelike robots. Over the years, the robots – called hosts – have been updated to look and act more human. As a result, the hosts have started to deviate from their programming. They've become unpredictable – just like humans.
