Dorian, <br>
<br>
From the cited Nature paper, it is about development, not evolution.<br>
Evolution is across different generations.<br>
Development is within a generation. Evolution cannot take place<br>
without development in each life. Do you like to change e-cyborgs
to d-cyborgs?<br>
<br>
Another comment is that if you had taken BMI 871, you would have had
very different views on the power of the <br>
"cyborgs" or what is reported in that nature paper. They miss the
basic set of developmental mechanisms (5+1 chunks) needed by <br>
a brain. Simply put, neurodynamics of a single neuron is far from
enough for any tangible intelligence. My estimate is that it <br>
corresponds to about 1% of the basic set of developmental mechanisms
needed by a brain: 5+1 chunks. The "area" chunk uses <br>
neurons, but the "area" chunk requires much more theory than neurons
that can connect and adapt. It is like a cell is very far<br>
from the brain tissue. <br>
<br>
I am not saying that 5+1 chunks are absolutely sufficient for a
human-like brain, but they are necessary from my understanding of<br>
their functions. You might want to take a look first:<br>
<br>
5 chunks: <br>

We would like to create a mind so smart that can find
solutions to extend our life. The path isn’t mapping the brain
(Human Connectome Project, NIH), replicate the brain
(Markham's Blue Brain) to shed light on the nature of
consciousness and neurological disorders . They are costly
projects which will provide little new insight.<br>
<br>
We already know that the real brain has a powerful way to
perform computations using processes happening at the
microscopic scale (neuroelectrodynamics). All these attempts
to replicate the human brain on digital computers will fail.
Cyborg scientists and not only them need to be honest
regarding their achievements (e.g. replicating behavior,
emotion, even consciousness on brain chips) and understand
that the Turing model has its limits -ultimately that's not
their fault. <br>
<br>
<i>We need to build a different path, less costly, far more
relevant for us</i><br>
