I see your point. Craig has done some work on Bitcoin and deserves respect for that. Even if he messes up now, it shouldn't change the value of his previous contributions. That makes sense - but yeah - the media will not see it this way. They have lost credibility (or would have if they had any) and now are out of blood.
Personally, I think he went crazy. Kinda like if Einstein published a 'proof' that the earth is flat, years after his theory of Relativity.
