Another glorious battle for the kingdom?
The amount of stress we endure is increasing because of our focus on efficiency. Stress is caused by uncertainty, more specifically, by doubts in our ability to handle something. As machines and computers handle more things that are predictable and certain, we are pressured to deal with more things that are unpredictable and uncertain. This inevitably leads to more stress. As soon as our tasks become predictable and certain, we automate them using our technology. The result of this process of streamlining is that we are increasingly called upon to use our, what I would call, irrational abilities, such as instincts, sensibilities, creativities, and interpersonal skills. These things are, by nature, unpredictable.
Take stock trading, for instance. When there were no computers to process the trades, the number of trades you could do in a day was limited. A certain amount of your work as a trader involved processing of paperwork, communicating with others, and doing some arithmetic; tasks that are predictable and not stressful. Today, a click of a button essentially takes care of all of those predictable tasks, and you skip right ahead to another stressful decision-making.
As another example, take graphic designers. Now with computers handling everything from typesetting, layout, image processing, color management to printing, what used to be done by several specialists are now combined into one person. The number of jobs one can handle in a year increased dramatically. Now designers spend more time being creative, and less time creating the final products. This may sound good, but in terms of stress and rewards, it is not. Because creativity is irrational and unpredictable, coming up with a creative solution can be highly stressful. Designers now have to come up with significantly more creative solutions per year for the same amount of money.
