The slides for C. Elegans are there. Much smaller and simpler, and i
think there's almost no way it will be done in under 8 months. (Even
the physics simulation of the external world and body in the fly's case
would take much, much longer than that. How is the virtual fly meant to
recognise the virtual jam for what it is? are you suggesting hardcoding
a symbolic 'this is jam' -> 'jam activates neurons 34 to 102' in which
case jam-analogues that would excite the real fly would not excite the
virtual fly, or are you going to simulate jam's molecular chemistry and
fly's receptor, in which case your computational needs just jumped by a
fair bit i imagine. Even in the C.Elegans case, i think this would be
harder than the neuronal simulation)

agreed, FWIW, but only inside the brain. for the external world, i'm
not so sure.
