I led my Zoom discussion session the other day. The next one is next week. I am now preparing my slide deck and snide, off-hand remarks. My thesis is that since 2007, the year which I mark as the beginning of Industrial Revolution 4.0, the many different ways in which humans all over the world, live, work and play, eat, mate and communicate, as well as die, has changed dramatically. Those changes have come faster, and have encompassed more of the people of the world than at any time in humans history.
