You’re right that it would take a literal revolution to make this happen. So I’m not really hoping for it. (I’m joking, basically; I apologize for ruining it somewhat by saying so.)
I’m motivated partly by the observation that people put meaningful time units, like the day or the year, on the same footing as meaningless arbitrary ones, like the second or the week. And also by the insight, from the excellent book The Measure of All Things, that no nation switched to the metric system except after a revolution. The closest thing to an exception is the United Kingdom, which switched after the loss of its empire. It makes sense, when you think about it, but it’s also surprising.
