The current Novamente version deals only with numerical inputs, and contains
no structures like
The first version that deals with human language input, may or may not
create structures like this internally on its own...
Such examples are used in the current documentation on the system, because
they're easy to write about. In the revised documentation they are relied
upon less because they proved misleading to you and some other readers.

I'd like to divide the "Transferable content" category in two
1) content that is explicitly transmitted through books, DB's, etc.
2) content that is *implicitly* transmitted through interacting with other
minds in a shared environment
2 is at least as important as 1.
Cyc tries to capture a lot of what is implicitly learned by humans, in
explicit form, but I am very skeptical about this.

In my view, the most important content of an AGI mind will be things that
neither the AI or its programmers can name, at first. Namely: *abstract
thought-patterns, ways of organizing ideas and ways of approaching
problems*, which we humans use but know only implicitly, and which we will
be able to transmit to AI minds implicitly through interaction in
appropriate shared environments..

Of course, this general statement is not true. Often, in software
engineering and other kinds of engineering, a very complex design is HARDER
to improve than a simple one.

It will think differently from humans, but in the early stages, it will
learn a lot of what it knows about "how to think" from humans.

I think that a lot of transfer of thought-patterns will happen *implicitly*
through interaction in shared environments.
For this to happen, explicit declarative knowledge of thought patterns is
not required, on the part of the human teachers.

I doubt this is how things will go. I think human knowledge will be
comprehensible by an AI *well before* the AI is capable of drastically
modifying its own sourcecode in the interest of vastly increased

I don't insist that everything is intuition. I try to carefully distinguish
between conclusions based on evidence, and hypotheses based on intuition.
Both in my own thinking and in the thinking of others.
(Of course, intuitions are at bottom based on evidence, but they integrate
large bodies of evidence in complex, hard-to-trace ways.)

Yes, we differ here. I think we will create an AGI with all basic dynamics
in place, thus creating a baby, which will educate itself up to
human-adult-level-intelligence, partly by interaction with adult humans in
I also think that, during this education process, we will discover flaws in
the AGI's "basic dynamics", so that engineering will be ongoing during the
teaching period. As teaching progresses, the AGI itself will be more and
more useful in helping improve its own dynamics (and structures).

I think that humans will teach the AGI more than just "domain problems at
the right level," I think that by cooperatively solving problems together
with the AGI, humans will teach it a network of interrelated
thought-patterns. Just as we learn from other humans via interacting with

The corpus of human declarative knowledge is useful to an AGI for two
a) directly, it's valuable knowledge
b) it gives a context in which far MORE valuable abstract thought-patterns
can be transmitted from humans to the AGI

I agree, it does not mean that an AI *must* do so. However, I hypothesize
that to allow an AI to learn its initial thought-patterns from humans based
on experiential interaction, is
a) the fastest way to get to an AGI
b) the best way to get an AGI that has a basic empathy for humans

I think this is
a) a less efficient way to train a mind than cooperating with it in a shared
environment [due to the fact that the latter allows more
b) a route much less likely to lead to a Friendly AI. An AGI that has
learned to approach context and problems by doing so cooperatively with
humans, and has hence absorbed human thought-patterns, is a lot more likely
to have a real empathy for humans as it reaches the transcension phase.

Yes, you see more "code self-modification" occurring at the
"pre-human-level-AI" phase than I do.
This is because I see "intelligent goal-directed code self-modification" as
being a very hard problem, harder than mastering human language, for

I don't have a strong argument that the transition from human-level to
vastly superhuman level intelligence will take years rather than weeks.
I consider "humanscale speed" as a likely upper bound (though not a definite
I don't feel you have a strong argument that the transition will be vastly
faster than this upper bound suggests, though.
Your argument was that "there's nothing special about human level
intelligence." I sought to refute that argument by pointing out that, to
the extent an AGI is taught by humans, there is something special about
human level intelligence after all. Then you countered that, in your
envisioned approach to AI, teaching by humans plays a smaller role than in
my own envisioned approach. And indeed, this suggests that if seed AI were
achieved first by your approach rather than mine, the gap between human
level and vastly superhuman level intelligence would be less.
