I kind of agree - but really let's say we listen to our inner doubts, we mutiny and throw Ahab overboard, we are still on a whaler in the middle of the ocean. Now what?
Our (global?) society is on course for destruction on the ocean - but that course is also sailing use closer to the promised land. Every innovation, every step closer to the singularity requires us to move faster, land more sure-footedly. Yes we could balls it all up, start a mindless war that tips the balance, refuse to cooperate in trade or keep the next Einstein in a poverty stricken barro to die of diseases we cure with a single needle.
but then we could not - we could survive on the knife edge - learn how to sail better, close to the wind.
Destruction is not inevitable - it is just somewhere between likely and probable. All the more reason not to give into dsspair - not let Ahabs obsessions distract him from the survival of the ship, but for us to watch and honestly discuss the ships course - and find a way for the whole world to choose together our next course.
(yeah a little too flowery language - sorry. it's late)
