How digital assistants change the way we search

The transformative power of technology is stunning. Fifty years ago, if you told someone you needed to search for a piece of information, they would think that you were headed over to a wall of encyclopedias at the library. Fifteen years ago they would have thought that you were going to go sit down at a bulky desktop computer to type something into a Yahoo search bar. Five years ago the image would include a smartphone in your hand, fingers tapping away. Today the idea of a search is becoming more and more synonymous with simply speaking out into the air.
