Four updates in one day were required because the first one did not record all of your keystrokes. The second one recorded all of your keystrokes, but not your mouse clicks. The third one got your keystrokes, browsing history, and mouse clicks, but did not capture and compress the microphone and camera data for retrieval by Google. A future version will get your fingerprints if you use the fingerprint sensor, all passwords you have ever used, and a DNA sample so that Google can offer you a more pleasant and productive web experience, of course.
