You are referring to the idea that building an AGI is about "simply"
duplicating the human brain? And that therefore the main obstacle is
having the hardware to do that?
This is an approach that might be called "blind replication". Copying
without understanding.
I tried to do that once, when I was a kid. I built an electronic
circuit using a published design, but with no clue how the components
worked, or how the system functioned.
It turned out that there was one small problem, somewhere in my
implementation. Probably just the one. And so the circuit didn't work.
And since I was blind to the functionality, there was absolutely
nothing I could do about it. I had no idea where to look to fix the
problem.
To do AGI you need to understand what you are building. The idea of
successfully replicating a system as fantastically complex as the human
brain, without first sorting out the FUNCTIONALITY -- i.e. the software
-- is a hollow dream.
(Not to mention that virtually nobody in the AGI community is actually
trying to do that right now. WBE is done by neuroscientists who seem
not to have thought about these issues much, and they don't call what
they do "AGO")

Track what the neocortex is doing? I am doing that. That is my
research.... except that I am doing it at the high-level, functional
level. What I am trying to do is understand how the neocortex works,
not how the signals are chasing each other around. Those are two
different things, like the difference between electronic engineering and
software engineering.
And, so far, it looks as though the cortex may be playing a functional
role that can be implemented with a few orders of magnitude less
hardware than the brain uses.

Well, we agree on this (as you probably know) for completely different
reasons.
At least I think we do. If you are saying this because you agree with
the critique in my complex systems paper, I will be a pleasantly
surprised person today.
