I need an antialiasing filter for generations. New cohorts of people rediscovering ideas that last came around a decade ago. It’s some sort of convolution of business cycle and micro-generational sorting effect chasms.

You wouldn’t expect this to be cyclic. After all the number of people turning (say) 24 and discovering some idea that’s peak salient at 24 is pretty stable. So why 5-10y cycles? Convolutions!

I’m getting a lot of deja vu lately re ideas that last came around circa 2009-11. Not quite sure why. Roughly same age group is discovering it (25-35). Some worse, some better, but mostly the same.
