Just when you think that some newfangled device is the best thing since sliced bread, you then find out that the awesome convenience you now rely on is actually making you less intelligent. This is called “Convenient Technology”. It turns out that human physiology is more complex than simply making some tool extremely convenient.
Just what is a demanding technology? Three elements are defining: it is technology that takes time to master, whose usage is highly occupying, and whose operation includes some real risk of failure. By this measure, a piano is a demanding technology, as is a frying pan, a programming language, or a paintbrush. So-called convenience technologies, in contrast—like instant mashed potatoes or automatic transmissions—usually require little concentrated effort and yield predictable results.
Disbelief is what I felt when I first saw two pedestrian texters walk straight into each other, head to head. So engrossed with their lives that they could not spend the time to watch where they are going? As a technologist I am always interested in the social effects of technology on society. Distracted walking shows that the vast majority of people cannot do two things at the same time, that multi-tasking is really not feasible for most people, and that this behaviour can be potentially dangerous to the person and those around them.
