Most of the things we use today have not been stress tested. They are centralized and have a single point of failure. And they are very vulnerable. It could all stop in an instant with no sure guarantee of when it will come back.
A turning point came for me visiting a small basement laundry in Manhattan. The proprietor was still using a sewing machine from 1948. She would have nothing to do with newer models. After that, I took greater notice of the machinery of other merchants in my area. Many sewing machines were 75 years old and still working well. My cobbler uses equipment more than a century old. This is not uncommon.
Are you ready for this sort of moment? What will you do when the lights go out, maybe for a very long time? I like to have some non-electric things around me. That may even look shiny. :)
