Via the New Yorker, Gary Marcus on how we will soon need our machines to be ethical, but have no idea how to do this:
Google’s driver-less cars are already street-legal in California, Florida, and Nevada, and some day similar devices may not just be possible but mandatory. Eventually automated vehicles will be able to drive better, and more safely than you can; within two or three decades the difference between automated driving and human driving will be so great you may not be legally allowed to drive your own car.
That moment will signal the era in which it will no longer be optional for machines to have ethical systems. Your car is speeding along a bridge when an errant school bus carrying forty children crosses its path. Should your car swerve, risking the life of its owner (you), in order to save the children, or keep going?
Many approaches to machine ethics are fraught [with problems].
