My apologies as I apparently failed to respond to an earlier post in a timely manner.
I am still not sure what is meant by AUM as the "stage of development" is it more like a part/structure that can be identified as existing even currently, or a transitional period that has evolved into something else by now?
A Google search brings up this as a definition for manifold as a noun:
noun: manifold; plural noun: manifolds
1. a pipe or chamber branching into several openings.
"the pipeline manifold"
(in an internal combustion engine) the part conveying air and fuel from the carburetor to the cylinders or that leading from the cylinders to the exhaust pipe.
"the exhaust manifold"
something with many different parts or forms, in particular.
What we want here is the second, technical, definition.
Now to clarify the reference to 'stage of development'. The LCS creates a general structure of the IUOCs interconnected by the RWW, which you seem to follow, based on mathematical processes of large systems known as emergence and self organization.
So now we have the LCS as a vast number of IUOCs interconnected and United by the RWW. This gives us the first term of AUO that Tom uses as an Absolute Unbounded Oneness as a term embodying these properties. Again if we look at the definition from Google, we get:
1. not qualified or diminished in any way; total.
2. viewed or existing independently and not in relation to other things; not relative or comparative.
"absolute moral standards"
Both definitions 1 and 2 can apply in my thinking.
Unbounded is used by Tom as he rejects infinite as being not real while unbounded just means that there is no bound to the possible growth of AUO.
Oneness means that it is interconnected and thus United into One thing.
AUO develops into The One Consciousness which Tom does not abbreviate into an acronym. This takes much time as the IUOCs develop from their initial state where they have a lot of entropy as bad code which must be replaced with functional code. All of the functions of logic and mathematics must be invented and developed over time. Communication protocols between IUOCs must be developed over time so that the are communicating in what must essentially be a single universal language. Eventually AUO develops Consciousness and becomes The One Consciousness.
So what we are doing is delineating the stages by which the LCS develops over much time. First it is just a vast field of data in reality cells. Then it develops into One thing which is United as IUOCs interconnected by the RWW. This is a matter of development and creation of new properties over time. And all of this is happening as the data in the reality cells is perking away and going through these developments being described. It is always just data in reality cells but new properties come about with the developments being described.
Now we don't have a totally definitive and detailed description of every tiny aspect and change of this very long development. After much time, AUO develops into The One Consciousness as all of the IUOCs communicating over the RWW start to function as and become Conscious: The One Consciousness. The One Consciousness perhaps becomes lonely or perhaps it just has a bright idea based upon self conscious introspection. That is it figures out that it is composed of all of these interconnected and interacting IUOCs. So its bright idea is to create a basis for the IUOCs to each have their own consciousness and to be able to communicate with each other. This took a lot of further development as each IUOC cannot actually be conscious on its own. It can process data, but it is not conscious of what that data is that it is processing. It has no inherent consciousness of its own.
So the next stage was for AUO to do some special processing within its own neurons/IUOCs in that it sets up what Tom comes to call The Big Computer, within which AUO creates the input to each IUOC for it to be aware of/conscious of. Now it's pretty clear that this did not likely happen as 'one feel swoop' and 'right off the bat' in English slang. There was a lot of experimenting, trial and error, and figurative 'head scratching' to figure all this out. This is where AUO developed itself into the 'chief scientist' that Tom has joked about or perhaps I should not say joked as it was a very real and significant development.
The Big Computer was probably originally all IUOCs or it could have been just some of them. This is lost back in the process of original development. Once we get into the Manifold aspect of having many Systems with ours being OS, then we have all the IUOCs within OS as being those who can communicate unequivocally as in no time problems as communication distances do not create confusions of sequencing in calculations. They then make up TBC for OS.
Nothing in the LCS or within a System as a subset is a 'structure'. It is all an ad hoc arrangement of IUOCs connected and organized by transient messaging over the RWW. This is what creates 'structure' as actually function within the LCS. Remember Tom talking about 'bubbling up' things as needed. This is how that it is done. AUM just sends out a block of messages that tell off a group of IUOCs to stop processing its own thoughts for a period and start processing some particular assignment instead.
But also keep in mind that all of this is 'ad hoc' and makes use of time sharing as in computer usage. A modern computer, even the one on your desk, has multiple processors (think IUOCs) and they time share a process as the computer's Operating System controls them to accomplish different parts of the work load in a shared and coordinated manner. AUM might be thought of as the computer when it is running the Operating System as the executive function that runs and coordinates everything else.
Has this clarified anything or just muddied the waters worse?
