People underestimate just how much effort goes into minimizing food waste and shortages in these types of industrial systems. The entire supply chain coordinates using these embedded sensors and control systems to make sure you always have safe food available at the lowest possible cost.

Connectivity in these environments is often challenging, it isn't like connecting a consumer fridge to wifi. Sometimes you are bridging weird networks that multiple parties need access to. It should be secure but that isn't as straightforward as one might assume. Many of these systems have very long lives, so there are many limitations that reflect the technology that existed when they were built.

All of this is invisible to the average person but it is what makes the world work.
