While I largely agree, you clearly haven’t explored the details of my worst fears, as all of them involve extistential risk for humanity, and do not involve the option of getting up and trying again. Failure is not an option that one can recover from in my case.
Thus I am persistent, in the face of little agreement, in promoting the idea that the single greatest risk facing humanity is the very notion of valuing things in markets, of exchange value, as it prevents the sort of universal abundance and freedom and security that fully automated systems are capable of delivering to every person alive.
And such freedom comes with responsibilities – to act responsibly in both social and ecological contexts for example, which means limiting family size – preferably to one child; as the possibility of indefinite life extension comes very close.
So yeah – wishful thinking, if not combined with planning and execution in reality, isn’t a reasonable or responsible behavioural modality, and it is certainly preferable to the sort of post modernist nihilism that some display today.
