Google goes peacenik, chip wizardry and AI gets into art and drugs

While we've already covered a lot of AI stories this week a few slipped under the radar so, as is traditional, here's the roundup of some news you may have missed. Google turns peacenik: Under fire for helping the US military use AI to better bomb people, Google has not only stepped away from that particular Pentagon contract but also this week released a set of seven principles for the development of AI. CEO Sundar Pichai made a point of noting that they are "not theoretical concepts; they are concrete standards that will actively govern our research and product development and will impact our business decisions." And they are pretty good: be socially beneficial (the AI equivalent of'Do no evil'?); They also sparked Twitter's CEO Jack Dorsey to ponder out loud whether they were something the tech industry as a whole could get around.
