① the frame-dragging metaphor is the result of still thinking in a crystalline space-time grid, if one uses a relative tensegrity of all bits in the universe, and time as immanent, all of relativity still applies, but there's less need to imagine gravity 'bending' curving space-time because it is already built in, so to speak
[relative tensegrity of all bits in the universe is hard to calculate -- I suspect the universe just does it without calculating.]
this doesn't affect your discussion, most know about bending space-time, but really there is nothing to bend but our prior crystalline Newtonian models of it
② one thing I have considered in the past with regard to big history is that we used to live, for the longest time, in small groups whose generational cohorts, at the same age experience more or less the same songs & rites, and that given teenagers interest in such things, and how impossible it is to even notice new music after the age of 35-40, then generational differences did not give rise to a generational clock with a strong tick-tock : golden, boomer, jones, X, Y, Z, millenials etc
However recently, given streaming technologies and the long tail of the backlist, the back catalog is available in its entirety (algorithms notwithstanding) to each and all new generational cohort and they can all now refer to the all same songs & rites (TV shows & movies in this case).
So we have returned to the paleolithic context. What divisions remain will be increasingly peculiar.
thanks again
