I just want to note that I work in utilities operation and repair for the US Gov't.
Have never had a "work from home" day. Never took a day off or spend a day at home due to Covid-.
i think there are more 'wrench turners' and electricians, electronic professionals, fabricators, - working for the Gov't than many people realize.
People are not affixing new machinery and systems, repairing + operating old systems + performing tests; onto ships, submarines, planes, in buildings and facilities, etc. - from the comfort of their kitchen wearing their pajamas.
Granted the folks I know work for DOD, and other agencies could be vastly different.
AI is not going to perform these requirements without people to perform the end tasks, and i've yet to meet a Robot that can remove a manhole cover, climb down a ladder into a tunnel or up onto a building roof, diagnose a malfunctioning pipe, pump, circuit breaker or control board, take measurements, order parts, replace them, test the unit and bring the system back online - so that co-workers can stay warm, or have electricity to run their processes...
