They most definitely did not get it right.
Having said that, there is some value to being thoughtful about the adoption of new technology. Especially when it comes to kids, some parents are too quick to allow their kids to use smartphones, tablets, chatGPT, etc. without much supervision.
But, the prospect of having to forego virtually all modern technology or become exiled from the only family and community you’ve ever known is crazy. It’s really only cults that require that you shun people who have left the “faith”.
Also, the modern Amish are the effect of multiple decades worth of Group Polarization. People in the community will hold different views. If someone has a view that the rules are too strict and that the group should be more lenient, they may eventually give up and just join the modern world. On the other hand, if someone thinks the group isn’t extreme enough, there is no other even more extreme group for them to join. So, they’ll stay and fight for their view. Over time, that means that the less extreme people tend to drift away, and the more extreme ones stay, leading to the group becoming more extreme.
