We all know Siri, and Cortana, and yesterday, when I gave a talk, and I mentioned the word Google here or there, a "stray" mobile phone close to the stage was happy to listen to my commands. We are getting used to talking to our computers, just like in the movie "Her", and the change in interface also changes the way we interact with the respective services. More and more, we are not entering "search terms" or "keywords", but are issueing commands. Google introduces this change also to the web search engine. You can make the search engine "your slave" - just tell it what to do.
