It's impossible, even for Feynman, to understand how to create everything. In your example the Amish idea of "we" is religious bias — each Amish individual doesn't know how to create everything, they choose to rely only on other Amish, shunning the knowledge of others. "we" can also take on patriotic bias, as in, "we" don't build anything anymore because it's all made in China, thus excluding China from that "we". The fading globalist dream of the 90s was that "we" could include everybody on our little planet.

That's not really true about the Amish. I've never heard that interpretation. It is more complicated than and Amish do use technology in limited ways but it boils down to not wanting to disrupt their family with technology and also the complicated process of integrating new technology into their lifestyles.

> it is that they Don't want technology they can't control, basically if unable to make from raw materials they don't want it.

Lots of Amish farmers use a computer. They just keep it separate, and don't let it invade their home and decide their life.

Think landline phone on a farm, but also the phone is in an outdoor phone booth and used only for unavoidable things like ordering seeds, not socially.
