I don't disagree, but I would suggest that if the "successes" are worth billions upon billions, then even "failures" are quite valuable as well, at whatever point in the processes they are still indistinguishable. As hard as economic value is to quantify, "enduring value" is even harder. So I won't even attempt to make judgments on that front.
