Ironic that the idea of the Sabbath that made it the backbone of the strength of the ancient Israelite people, the notion of a forced day of rest for the worker, has now become so totally trivialized, that it becomes nothing more than a way to learn some sort of arbitrary anti-technology self discipline.
This article in the Jewish Standard, pulled from j. the Jewish news weekly of Northern California qualifies is our estimation one of the worst ever written about any Judaic value or subject, "Disconnect to connect: Sabbath Manifesto urges the Google generation to unplug and slow down."
As we see it, this manifesto described in the report, and all related to it, is not in the least bit what the Sabbath is all about. For most people the technology of our times is integral to both work and rest, to both productivity and diversion. Learning to relate to technology and use it properly does not happen when you totally ban it for one day every week. There is no insight in the free association of ancient Sabbath taboos with modern kvetching about your children texting all the time.
Just accept that we need for children and adults to learn the propriety of sexual relations without the apologetics about the absolute genius of the mechitza separating men and women in the synagogue. We also need to learn how to properly relate to technological communications without the apologetics of the brilliant foresight of the Sabbath restrictions of ancient times.
Ironic isn't it? The Sabbath, part of what made our people the most admired in the world in ancient times because it relieved the worker one day a week from the actual slavery of daily toil, now makes our people look utterly idiosyncratic, no matter the apologetics reported in the press.
The actual reasons for Sabbath observance in modernity are difficult and absurd, not based on convenient coincidences between some oddball notions of what is good for you, but on the actual ancient taboos that we keep because we believe the Torah was given to Moses on Mt. Sinai and we were commanded to observe it.
