This is just a quick silly story that illustrates how the "intelligent" programs that monitor our lives can be both funny and creepy.
At my work, we have an intranet application -- something that runs in a web browser, but it's only visible from inside the office -- which tracks change requests and bugs we are working on. I am on the Client Account team, so most of my projects are identified with "CA-" and then a number, such as "CA-1234."
Usually after I have been working on one project for a while, I have memorized the number, and so I just type "CA-1234" into my browser. Since I have visited the feature page often, it automatically fills in the URL to take me there. But sometimes I mistype, or it doesn't work for some other reason, so my browser helpfully pulls up a Google search for CA-1234 instead.
That does not contain any information that is useful to me. However, it does often match a flight number on China Airlines.
So one morning I got an alert on my Android. It was Google's calendar program. It told me "It's time to leave for the airport if you want to catch that flight on China Airlines that you looked up!"
