But do we really know how do minds work or we are going to just code
whatever we know
and hope that whatever we'll create turns out to be a mind?

Does any mind use code? It seems to me that the main purpose of code is to
keep a record of the structure so the AI will have the access to that code
once it knows how to manipulate it.

Okay, but what is the nature of concepts? What will be the "code" of a
concept. They will not be run through traditional compilers, I assume, are

Next, what is the nature of the "computation" that might be performed on
those concepts? How should interaction between concepts look like? If you
load "lightbulb" and "triangle" and want to create "triangular lightbulb"
inside the mental workspace, what will need to happen between the two chunks
of code, and more importantly, how will it contribute to intelligence of the
mind? In other words, how would we know that implementing concepts and
workspace creates an intelligent system rather than sophisticated
representational system.

And what mechanisms might govern reasoning with the structures made of

If the concept is proposed to be a list of features, then how would those
features interact with other features to produce something meaningful?
Wouldn't a mere list of features lack the "substance" that all
conceps/symbols necessarily require?

I think we have a good direction, but lack the means of reaching the
