Or more things will happen like the Bhopal disaster where a chemical plant, over a decade or so, laid off or failed to replace everyone who knew what their carefully designed multi-layered safety systems did. When those systems aged and needed maintenance, the remaining production people took them out one by one. Then 500,000 people were gassed with cyanide. 2,200 immediate deaths. https://en.wikipedia.org/wiki/Bhopal_disaster
