tehta, while I have known some hardline Pagans who try to avoid technology as much as they can, I have known others who embrace it and even work with it. I think for many of the neopagans there are no established rules, it seems to be more a matter of what works, or doesn’t work, for them as individuals. Most of the systems I have encountered that do have rules about such things tend to be the old and crusty systems, and even those sometimes adapt down the centuries! My own view is that the technology is neutral, and the use made of it is what matters. And that computer example is amusing!
Plus at least the Celtic ones allow for circumstances in the world. For example, in many of the Celtic systems it is not considered right for a mage to be a mercenary soldier or part of a peacetime standing army, but is perfectly permissible to be a soldier in a war in which one’s own country is threatened. And even in ordinary circumstances some users of Celtic magic have been non-combatants within the military system- I have known three who were army field medics, one who was a military bandsman, and several who were nurses or doctors in military hospitals. I think it has to do with the attitude to taking life, and to jobs that put someone in a position where power could be too easily abused.
The arts are generally okay, along with music, dance and other performing or teaching arts, and the ones that involve some sort of service-to-humanity task - health care, education, and suchlike. One senior druid worked for many years in a program educating people who were in jail to the point where they were literate and numerate enough to get and hold a legal job, since the lack of such skills is an all too common reason for people winding up in the prison system. Seems to me like a service to humanity thing to do.
