The urgency isn't even in block size or scalability. The urgency is in fixing the goddamn decision-making process among the core devs. You think Hearn was wrong about that?
From an objective standpoint, looking at Hearn's contributions as a whole (the database change that caused the first fork, the redlisting coins proposal, and XT in particular) I think one could come to the logical conclusion that Hearn has been compromised by the NSA or some other three letter agency, likely recruited while he was still with Google.
Oh get real. Insisting on personalising the debate is childish - just stick to the technical and practical issues that we are discussing.
And keep your ludicrous tin hat theories for you're evenings in your fallout shelter, counting your ammo and tins of spam with your militia buddies.
