No. 2 Son, 12, has always been curious about how things work. He’s currently fascinated by computer operating systems. Yesterday he asked which was the worst version of Windows.

Which led me to talk about how difficult it was to get people to upgrade from Windows95, tools that are good enough, planned obsolescence, creation of demand for useless things, tailfins on cars, fast fashion, and the insanity of an economic system that relies on creating wants and cannot satisfy needs.

Good times!
