My impression was that the author was referring to *self-amplifying like a positive feedback loop.

I agree I would have loved more of a hard / concrete definition oriented approach to the whole piece but everything they were saying really resonated at least in terms of my personal experience. I haven't ever come across a writer focusing on this. It was really unexpected / refreshing. It's already is reshaping little moments in my day like hugging my son just now. Very unexpected transcendental value for an HN skim while ignoring a boring zoom standup. The truth is out there.
