An android child struggles to control his emotions. Robots threaten to take away human jobs. And a voice-activated device ponders its own existence.
These dark themes were explored by this year¡¯s Super Bowl commercials, with brands such as TurboTax, Olay and Sprint capitalizing on fears that technology is encroaching on our lives.
