We're human...everything we attempt involves other humans... Most "intelligent" humans think, at some point, that the way we go about our lives, on this planet, could be improved upon... How to build consensus...? How to design a series of universal (planetary, in our case) truths that all will immediately recognize as valuable, and be willing to live by...? Tons of obstacles, because we're human...tribalistic, nationalistic...we're short-sighted, likely by nature...
