All these kinds of pedestrian worries are horrible enough, but the Edge list makes it clear that we haven't considered all the delicious possibilities out there.

I had no idea, for example, that I needed to be worried about "data disenfranchisement," as David Rowen, the editor of Wired UK, suggests, or the end of what Adam Alter calls "hardship inoculation."

I was amazed at how many smart people (psychologist Susan Blackmore, MIT researcher David Dalrymple, roboticist Rodney A. Brooks) were worried about robotics. While I have wasted far too much time worrying about "men," just as biological anthropologist Helen Fisher did in the survey, and "stress," as aggregator Arianna Huffington responded, I don't think we are talking about the same things.
