I see. You were implicitly assuming that every theory must eventually fail. I certainly sympathize with the idea that there will always be new frontiers to explore, but that's still a rather ideological assumption. Steven Weinberg for example does not seem to be afraid of the idea of a "final theory".

Yes, indeed! Weinberg's an particle physicist, whereas I think I've been reading too much of XiaoGang Wen's wonderfully mischevious "condensed matter" viewopoint
Anyway, if Asymptotically Safe gravity is emergent, would you then expect it to emerge via an infrared 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 EinsteinHilbert 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?
