“Some people think the Amish are against technology which isn’t really accurate. It’s more that they’re intent on being self-sufficient and against unnecessary uses of technology.”
That’s not really accurate. They do have great respect for self sufficiency, but that’s not why they eschew technology.
They do it for religious reasons. They, much like the Jewish Hassids, have chosen a heyday from their past that they believe god wants them to adhere to the restrictions and customs of.
If they thought god was cool with iPhones, they’d get one tomorrow, self-sufficient or not.
