Which artificial intelligence applications will flourish by 2030?

For decades, artificial intelligence has been depicted as a sinister force in science fiction. Think of HAL-9000, the main antagonist in Arthur C. Clarke’s Space Odyssey series. But while applications of AI and machine learning are indeed sophisticated and carry the potential to be dangerous, my own view is that over the course of this decade, the most frequent encounters people are going to have with these neural technologies will seem both ordinary and positive.
