We Created a Harry Potter 'Clone' to Let Humans Talk to Computers

Have you ever talked to your computer or smartphone? Maybe you've seen a coworker, friend or relative do it. It was likely in the form of a question, asking for some basic information, like the location of the best nearby pizza place or the start time of tonight's sporting event. Soon, however, you may find yourself having entirely different interactions with your device – even learning its name, favorite color and what it thinks about while you are away. It is now possible to interact with computers in ways that seemed beyond our dreams a few decades ago.
