We have the semiconductor technology to build a brain.

out to be of manageable, albeit ambitious size]
Agreed that we have no idea how to program such a piece of
machinery to be intelligent. But it could be built today.
I think you compare apples and oranges. Sure, the raw compute power
could be marshalled - this has been true for some time, though as you
point out, it's getting to be within the scope of a realistic (?)
research initiative (;^/.
Brains do things that hypercubes don't though, which is learn, and
that learning is reflected in the topology. Further, there's a
non-binary (analog) aspect to the information transmitted.
Might be interesting to redo the calculation including NN architecture
(such as those being developed at Bell Labs) and/or analog modules
(no-one is interested for these at the moment, so far I know).
NN-stuff doesn't adequately provide for the representation of time,
though, so you'd have to keep some TM aspects, and how it is organized?
Topology changes as a product of learning? Seems quite open to me,
but I'd like to hear of efforts in this area.
