I really don't get what that other pinhead on the list is talking about
with his 4 column chart with computer chips in the 3rd column...
If you want to talk about doing science on <zombie voice> brainz
brains..... </zombie voice>
Look at the gdmf Cerebellum.
It has two dominant cell species:
Granule cells?? -- Ok, a dorky little cell with an axion that shoots out
to the cerebellar cortex and extends out horizontally in two directions
and creates what are called parallel fibres:
The other kind of cell is the Purkinje Cell, these are the largest type
of cell found in the brain, they *typically* have around 150,000
synapses, (NOT A TYPO!!!)?? There are around 4 million of these suckers
in the cerebellum (iinm), or at least a number on that order of
magnitude. This is not something that you will want to simulate in great
detail. The stupid uploaders seem to be crazy enough to want to try, but
it is not something you want to do to get smarts.
So what does the cerebellum do??? It looks kinda like a player piano,
where you can think of granule cells as the scroll and the purkinge
cells as the notes. But actually what it seems to be doing at a high
level is basically calculus.
So what does the cerebellum do? -> a crude, buggy form of calculus
according to a number of authors and the types of deficits shown by
patients with cerebellar lesions. -- they try to reach for something but
fail to do the calculus required to sucessfully stop the hand (which has
mass and inertia) at the intended target.
Well, we can math, or at least some of us... So therefore we only need
to encode in all the variables that we need to calculus (both physical
and higher cognitive functions), and then use some mathematically sound,
computationally feasible, way of doing it to far greater precision than
possible in biology, and then decode the output back to neural impulses...
So therefore by doing math instead of detailed emulation, we can
probably shave 10 years of hardware development off what we need to
reach human equivalency, and years more off what the uploaders will
probably need.
