Tangentially, this part brought up an early thought that I had: tapping into a qualified workforce that for some reason got removed from work standard work opportunities. One such large group the one mentioned (at the time in the UK, probably less applicable now).
Another one that I usually think about is all the people with high levels of manufacturing expertise that got laid off in the US in the past decades, living in smaller towns. Would it be possible to tap into their knowledge remotely?
