All these virtual personal assistants are incredible, if slightly creepy advances in technology. Just speak into your computer's microphone, or into your smartphone, and just like that your personal assistant is answering your questions.
"Is my flight canceled?" or "How do I get to Wal-Mart?" In seconds, your virtual assistant is speaking back to you, with the answers you need. That's just touching the surface of what these powerful voice-command systems can help you with.
In fact, we recently told you about features and functions on Google Now that you're probably not using yet. With Google, you start your questions with "OK, Google," then go from there.
OK Google will answer everyday questions like, "Did the Dow close up today?," to more important stuff like, "Call Mom," or "What is 5,000 euros in dollars?"
That's cool. So, what could possibly be the problem with "OK, Google?" Well, there's this: Google is listening to you right now.
