I worked at the Post-PC lab in Colorado for a while. The premise, at least when the term was coined, wasn't ever that Desktops or the new (at that time) "Pen Computing" interfaces would ever go away. Rather it was always that "computerization" would invade all walks of life until suddenly everything would become computer. Much of the research we did was looking at life would be like when suddenly everything you interact with would have a programmable interface, rather than only being able to program things through your PC. 30 years on much of that has turned out to be more or less true with cars, lightbulbs, door locks, and so on. But of course like all "predictions" of the future it's made using the terminology that was in vogue at the time and sounds funny to us now that it's here and other terms like IoT eclipsed their popularity.
