Episode 3 part 2

While watching this video, I was shocked when I saw what happened with the advertizement with the google mail. I don't understand how the computer can read out our messages and then even find related information about that topic for us. That just blew my mind. I think in like 5 years, everyone will own a computer like how most people own a house right now. I think all the businesses are all going to be online in the future and people with the best pay salaries are not going to be lawyers or teachers, they are going to be people who can work really well online.
