is privacy an illusion?

Yes privacy is an illusion, with all the high tech and all the hidden programs a such, and 80% of our lives is dedicated to electronics and such, I believed that there is no longer privacy. Just look at Google, Google stores history on every website you use on it, so Google can know what your hobby is what time you actually do your homework, and information you don’t want to share to people. Secret intelligence now have spy drones and satelight tracking. The US governemtn even send a picture og Gadaffi taking a dump just to warn him! Who is to say that the government wont do the same thing to us? With so much high tech the government can easny snuck in a spy ware for every computer and get in data, and there is a very high possibility that it can access the computer’s camera and take a photo of u to spy. I Know I sound lieka  conspiracy theorist here, but all of theses are highly likely and easy to be achieved
