Ah, so he's an idiot.
Pretty much. He seems unaware of the huge selection bias--and logical contradiction--implied by the claim about "the inability that humans have exhibited in rectifying uncontrollable catastrophic challenges"
We've dealt with a huge number of challenges successfully, but a pretentious git like this would never even be aware of them, so his estimate of our track-record is off by light years.
Bacterial disease: rectified.
Unwanted pregnancy: rectified.
Growing enough food to feed ourselves: rectified.
And so on.
Sure there are hard problems left. They will be solved by engineers, scientists, bureaucrats and businesspeople willing to take risks and test ideas by publicly testing them via systematic observation, controlled experiment and Bayesian inference, not pretentious gits telling us how awful we all are.
