Still so early

Lunch yesterday with a long time colleague who has significant board, corporate and public sector experience and acumen. One of the smartest people I know .. yet dismisses Bitcoin as "Greater Fool Theory"

Realised I'm past the point of explaining gaps(chasms) in peoples' understanding where they've "reached a conclusion", unbounded by any actual research or effort. Genuine questions .. I've got endless time

Done wasting my precious time with those who are unteachable
