Good point, Carroll distinguishes between "manifestations of the underlying laws" and the laws themselves. Still, this is an impossible claim to make, because you can't prove a negative. Given all these everyday phenomena we can't explain, it is entirely conceivable that one of them will require a modification of QFT. Personally, I think that consciousness or memory (which we all experience every day!) could rely on weaker interactions than the ones we know of. I find it unlikely but certainly possible that we aren't yet mathematically capable of predicting conscious behavior.
