THE WORLD IS STALKING ME

So we got into class and we were told how creepy GPS is and that everything that we have is stalking us. Things like Alexa that hear everything that we are saying and record it. This is just super scary because random people could know what you are talking about at all times. Also, on ancestory.com, you log in and give them a DNA sample to find your history. They could find out everything about you just by a DNA sample. If you have a higher chance of getting cancer then that could mean that you don't get a certain job for something that isn't your fault and all because people are disrespecting your right to privacy.
