Simply that a truth value being attached to a theoretical trend because 'it's been running for the past forty years' strikes me as mere subjectivism. As to ''matching existing tested models' consider the vast number of events taking place during, say, a cyclotron collision at CERN. There are so many only a small proportion can be detected and recorded. This engenders the creation of specific software aimed at detecting a limited range of anticipated events. Self fulfilling profacy could be one result.
"Why do we live in a universe that's just on the edge of stability?" Because the form of life we represent can only exist in such a universe? Because ( excuse me hinting at something potentialy theological) the 'Creator' of our universe finds such realms more interesting than others? On a more serious note why should we reject any proposition simply because it 'runs against the theoretical trend of the past forty years,'
"The level of expertise that most rationalists strive to develop is not on a par with the skills of a professional mathematician - more like that of a strong casual amateur." Are we to assume that professional mathematicians are always to be regarded as the ultimate practitioners of rationality? Given the number of dead ends achieved through pure mathematic theory in attempts to forumulate 'a theory of everything' is it not worth considering althernative methods? As to 'sequence reruns', 'meta discussions' etc agreed definitions of these terms are I suggest not to be taken for granted.
