I’m old enough to remember the market crash of 1987 and all the subsequent ones. At the time, I was working for a commodities trader in London, my first job out of the army. The tech industry didn’t exist yet, there were only early signs as to what would mature into a full-fledged industry in the late 1990s, just in time for the collapse of 2000 and the drama of 2008. Each time it felt like the world might grind to a screeching halt.
