Yes. AFAIK, this is exactly the (theoretical) cause for the "doomed to repeat it" effect of "those who don't learn from history are doomed to repeat it" - the death of the last generation who remembers it from the previous iteration.

So - maybe not doomed to an 80 year cycle, as life expectancy changes, and/or as cultural memory changes due to more/better records.

But in broad strokes... yes.
