I’ve just had a whole bunch of fun at the Melbourne Singularity
Summit. What a ‘hoot’!
At the conference I made a somewhat thwarted attempt to introduce
physical replication as a ‘roadmap item’ for AGI. I tried to show that
AGI may be reached by constructing the actual necessary physics of
brain material using different ingredients (inorganic cells and
electrons instead of ions as charge carriers). This proposal has
critical superiority because it can be argued to retain all the basic
physics of brain material and therefore inherit all the natural
properties in the manner of brain material. In such an approach, the
chips would have an EEG and MEG signature like brains. The chips can
be argued to be making use of quantum field effects just like brains do.
Your proposal seems to be saying 'yes' to the doctor who promises to
replicate the EM fields of your brain. But if EM fields are what do the
thinking then one's thinking would be muddled when you stand near power
lines. Of course at the atomic level the EM fields of outer electron
shells define the chemistry - but then it's simpler to describe the
brain functions in terms of the chemistry.

Such chips (=physical replication) have zero simulation, zero
modelling, zero computation, zero emulation, and are not synthetic
biology.
Which leads me back to the IBM offering.... the IBM contribution will
underperform because it uses models. If an ‘artificial brain’ were
like ‘artificial fire’, then the IBM offering would be like claiming
to have made fire by pretending to have fuel or oxygen. I would hold
that the IBM hardware is not ‘artificial brain material’ and therefore
will be missing key properties needed for full cognition.
I’ve been trying to get the physical replication idea across to
various people as best I can. I am making slow progress. Please
consider it an available AGI option. I am still trying to work out why
no-one else has tried it before. Everybody has been assuming since the
1950s that AGI involves computers. I’m here to undo that mindset to
the required extent and get more balance in the approaches. Let’s bake
the AGI cake with real ingredients so we actually end up with
artificially-originated, yet still quite edible, cake.
I’ll be at the EMBC 2011 conference in Boston next week. If any of you
folk are around, come by! I have a poster on Tuesday.
