This wall of fog and state of "not knowing" is brand new in human history. Thus, it's more important than ever to keep an open mind. A great thought experiment suggested by [[Bryan Johnson]]: 1. Think of folks from the Middle-Age and how some of their beliefs sound false and even ridiculous nowadays. 2. Think of people centuries ahead of us... 1. How will they look down at us and rate our current beliefs? 2. What ideas do we take for granted that could be torn apart in the coming centuries? 3. What ideas sound stupid today but could prevail and become a norm later on? => [[History is a logbook of humanity's trial and error]]
