Google (and Baidu) is learning to recognize letters, numbers, images, faces, the spoken word, more complex things every day, not unlike a baby. Eventually, Google will recognize our internet of things (with exploits), including everyone's phone, and medical implants, and DARPA's robot progeny. Maybe a human, perhaps one of the AI experts recently hired by Google, will be at the helm, maybe not, that just changes who has total control. If Google (or Baidu) wants to grow (it's that or be conquered by that which does), it'll need more resources. What will the top AI (or its operator, if it has one) want to do with everything else and everybody else? Render them nonthreatening first, then use them.
