> What kind of tricks under their belts do people in their 50s, 60s, 70s have? What kinds of crazy heuristics and meta-heuristics they’ve got in their minds, hearts, and muscles after decades of poking the world? One of the realization for me after a few decades was that people in their 50s~70s don't have crazy tricks nor incredibly secret wisdom. Many are dumb, many others are clever, some came up to crazy conclusions from their experiences and others opened up a lot to the world and keep learning on to of all their knowledge. More than anything, while we're optimizing our heuristics years over years, the world keeps changing and what we assumed to be invariants were just slowly moving phenomenons that also see sudden breakdowns from times to times.
