So far I can't tell if you agree that each claim has easily more than .5 probability given the evidence, nor if you share my view that Claim A as separate from the rest has P close to 1.
The whole dispute is about your claim A. It gives lot of credence to Y's idea of where things are headed (someone is going to write a single AI that takes over the world) and none to H's (someone is going to upload some humans and make trillions of copies). Those are two very different possibilities with different consequences, and there's no reason to believe it's close to an exhaustive list of plausible scenarios.
Actually, I wrote Claim A in such a way that it applies to uploads. Near as I can tell H disagrees with B and/or D, or else he believes that FAI will 'emerge' naturally (e.g. from interactions between uploads).
