Yes, indeed! Weinberg's an particle physicist, whereas I think I've been reading too much of Xiao-Gang Wen's wonderfully mischevious "condensed matter" viewopoint
Anyway, if Asymptotically Safe gravity is emergent, would you then expect it to emerge via an infra-red fixed point from string theory or AdS/CFT? I know gravity in those theories has a different dimension, but if we take the naive expectation from Litim's results, then the fixed point would exist in higher dimensions too, wouldn't it?
If I read your paper correctly, then you'd agree with Dvali and Gomez's http://arxiv.org/abs/1005.3497
that Einstein-Hilbert gravity would emerge as a limit of string theory, but you'd differ in saying it emerges in a Wilsonian sense, via a phase transition?
