Alvin Toffler wrote a book called “Future Shock” back in 1970 which posited the premise that individuals and society, as a collective whole, was experiencing a psychological syndrome akin to post-traumatic stress disorder (PTSD). This had been known to first World War (‘the Great War’) as shell shock, from living in fear of artillery shells exploding nearby. You never knew when something was going to blow up, nearby, or far away.
