You might look into what Amish life is actually like outside of movies. Most depictions in the media tend to at best be caricatures of our most conservative sects like Schwartzentruber Amish. Beachy Amish, Schwarzenau, even Mennonites have some conveniences; a computer is just a tool of my trade. Each community inside each sect will have its own Ordnung, which is just a mutual agreement on values and conduct when it comes to community. I like to joke with my English friends that we're the original neckbeards :)
Here's a good depiction of midwest Amish and the diversity in their communities. https://www.youtube.com/playlist?list=PLEyPgwIPkHo7lOk-72-tX...
