Another argument that fails is that sufficient amount of evidence might possibly cause convergence of some priors—but first our evidence for gray goo or fai is barely existent in any way, and second even infinite amount of evidence will leave far too much up to priors—grue/bleen Bayesians will never agree with green/blue Bayesians.
Even if Aumann threatens to spank them and send them to their rooms for not playing nice?

Aumann assumes shared priors, which they explicitly don’t have. And you cannot “assume shared pre-priors”, or any other such workaround.
