I will say this directly to make things clear: Mike Hearn is an idiot who sold himself to the banks. It's as simple as that. If I recall correctly, they knew at that R3 conference (there's a video about it) that the negative blog post and article (from NY times) were coming. It was planned.
I dont think bitcoin is dying somehow.
In other words: He was spreading hyperbolic FUD. I remember the time when Bitcoin "required" 20 MB blocks or it was going to die, and yet here we are.
Mike Hearn's anger and disappointment probably got the better of him but this doesn't mean that his statements hold water right?
He has the same amount of credibility like Gavin does now. None that is.
For those that are reading this, watch the following video for a free laugh:
