Fucking disgusting. Read the Forbes article it links to for even more. Imagine a future in which the Google 'algorithm' determines that you're higher risk of certain health conditions, and this prevents you from getting a job. Or gets you fired from an existing one. "For your own safety" of course. Now imagine Google having the power to alter these records for anyone it chooses. Complete control of every individuals life, livelihood, and fate. That's the end goal.
The ability to destroy an individual or group with the snap of a finger.
