People have always gathered information in a variety of ways — from talking to others, to observing the world around them, to, of course, searching online. Though typing words into a search box has become second nature for many of us, it’s far from the most natural way to express what we need. For example, if I’m walking down the street and see an interesting tree, I might point to it and ask a friend what species it is and if they know of any nearby nurseries that might sell seeds. If I were to express that question to a search engine just a few years ago… well, it would have taken a lot of queries.
