Of course; because if you plug in digitized neuroanatomy into
a sufficiently low level of theory the resulting behaviour will
contain all the upper layers by way of emergence. So you can inspect
the simulation to obtain the unknown unknowns.

So you say that you choose to simulate the functionality you don't
know at a level of theory you don't know to be sufficient. And you
can't tell us anything about that, orelse you'd have to kill us.
Sorry, that's enough of known unknowns out there already.

I'm getting your point just fine. It's just I'm not buying any of it.
Especially, since everything you say you do is secret.

It could happen, but I'm not holding my breath.
