Huffington Post article on DeepMind-requested AI ethics board, links back to LW [link]

Not going to summarize the article content, but I think this is the highest-level publication linking to LW so far.
Also, it's appears that Shane Legg, Jaan Tallin and others at Deep Mind leveraged the acquisition and moved the friendly AI conversation to a higher level, quite possibly highest level at Google. Interesting times, these are.
From what I gather, it is chiefly Sergey Brin who is concerned with ethical issues, and his attention is on various Google X projects. Larry Page and Eric Schmidt don't seem to care as much, if at all. That's probably one reason Google has been getting visibly eviller in the last couple of years. Unless Deep Mind is a part of Google X, I would not expect the ethics board to matter.
