Writing in Nature, Roger McKinlay notes the complexity, infrastructure requirements (i.e., cost) and limitations of modern navigation technology and argues that people “should make better use of our innate capabilities. Machines know where they are, not the best way to get to a destination; it might be more reliable to employ a human driver than to program an autonomous car to avert crashes. If we do not cherish them, our natural navigation abilities will deteriorate as we rely ever more on smart devices.” [via]
