It is a beautiful article, and shows that MRI is extremely
versatile. I disagree with the quoted researcher about the surprise;
all anatomical data suggest that fiber tracts are neatly ordered, they
just look tangled under a microscope. It would be much more surprising
if the tracts were random.

Unfortunately, this is not necessarily true. If I see a complex
pattern of activity in your brain, I cannot tell if it is you thinking
of strawberries or killing me, despite the orderliness of the
long-range connections. What individual neurons represent is likely
highly variable, and hence a pattern of activity that might in one
brain correspond to murder would in another be strawberries.

It might be interesting to think of religions that AIs might believe
in. Maybe something like the Dust Theory of _Permutation City_?
