Using the examples above, some may say it's detrimental because the introduction of technology has cost jobs. However, I see it as a reallocation of labor. In Rathe's example, the 9 positions that are no longer needed are filling other needs somewhere else, thereby increasing overall (on a national GPD level) production and efficiency. Technology has not caused job loss, it's just shifted it and promoted a culture/need for workers with higher skill sets.
Do you remember back in the day (I'm a child of the 80's, so that's what I mean) if you wanted to order something from a catalog, it would often say 10-12 weeks for delivery and that's what was expected. Then as computerization started to take hold, it became 6-8 weeks, 3-4 weeks, and now if we can't have it in 2 days or less it seems like we're waiting forever. This is just another example of increased efficiency promoted by technology.
