FWIW I interned at a US nuclear plant. They intentionally don't upgrade to digital systems for fear of being hacked, everything in the plant was analog when I was there 6 years ago.
Good for them!
These vary from simple “smart” light switches, to machinery used in industrial plants
This line makes me cringe. Current IT infrastructure are just NOT secure. Until the major IT tech companies and nation state can prove otherwise, important machineries, especially nuclear ought to be kept off internet and digital system.
