I recently found out that Google spies on people through their web cams

So if that bot knew what the girl was eating, I wouldn't say it's that big a deal. For Google it's their job to stalk people. For example the microphones pick up what you say, even when you think they're turned off. Then Google can show you ads that have something to do with what you were saying.
I haven't tried it myself but I'll just assume I'm always observed and listened to and stay a little bit paranoid :3 But I don't care, I don't talk that much XD
