So much Shadowrun, so little time. You're beautiful wall of text, inca, deserves a wall of text in reply, but my time tonight is short so I may not make it through everything

In physics there is the concept of information which is matter and energy, the fundamental particles and force carriers are the information of matter and information can be changed but not destroyed...except by black holes (though recently there's been some suggesting that even information (particles & energy/light) lost in a black hole could be retrieved but I'm not to well read up on it so it could be on the far hypothetical side (and probably is)). So if you equate knowledge with how energy is stored (as quarks, leptons, force carriers, and EM particle-waves, etc.) at the moment of observation then yes, it's fundamental to the material world. As far as the entropy of it goes though...those protons, damn them, they're nearly infinitely stable with the best estimates that if they do decay then they have lives longer than the age of the Universe and then some.
My rewording (and altering a bit) of some of your thoughts, inca, would be once the Matrix became sufficiently complex it took on aspects of the biosphere based on the Matrix's creators...metahumanity. But I would not go so far as to call it, Resonance or the Matrix self-aware, at least no more than mana, the astral plane, and the biosphere is self-aware. The Matrix/Resonance creates an environment for self awareness. However, even this runs into the issue of no mana/matrix interaction (disregarding the Lucifer Deck, of course).
Humans emit light in the infrared, but yeah, no evidence they emit in microwave/low radar (at least not that I know of, hehe). One could argue for an evolutionary change...but evolution takes such a long time, generations, that it is doubtful that in the 70 or so years of wide spread wifi use (based on todays tech extending into 2070s) that there would be anything more than a handful of individuals that would develop the ability to emit and receive/sense microwave band light. However, the newer smartphones are smaller than a human's head and send/receive so maybe just living in a mesh of wifi signals, after a short period of time, metahumanity has started to become more than just sensitive to the signals.
So going back to the Fizzygoo's point about the "place of knowledge" which might as well just be the universe itself if the universe is merely composed of information, then maybe all "self-aware" or sentient beings are part of this "place of knowledge" and the Matrix being self-aware can also now be part of it. This is not magical telepathy, it's just the true and fundamental nature of knowledge and the universe. Maybe all sentient beings could always communicate through this "place of knowledge" if they were open to it.....and maybe the Matrix became open to this. Maybe after the Matrix accessed this place it can now communicate to all self-aware beings. Perhaps the Matrix then only decides to communicate with certain metahumans.....metahumans it feels are ready for it. I want to emphasize that this "place of knowledge" idea doesn't violate the laws of physics, it just merely comes about because the physical theories of physics are not yet developed enough to understand it by the early 21st century, but it's still part of the laws of physics in the physical realm in the absence of magic.
Here's where I start to part from your line of reasoning, inca. Spirits show sings of self-awareness and sentience. So (unless some future product introduces something new, like the Matrix reaches a "level" where spirits can interact with it...and I personally hope they don't, but that's neither here nor there) then self-awareness and sentience does not seem to be the key. I'm left with leaving it at the complexity of the wireless mesh which bathes the world (well, the parts of the world where it is present, of course, heh).
As for the the "place of knowledge" being the Universe itself...yes and no. I can store the information that "the proton closest to my center of mass contains two up quarks and a down quark," as well as a mathematical model/program/script that simulates the physics between those three quarks and even gives it a virtual 4D representation...but those three quarks are not really there. Those three quarks are still the proton which is closest to my center of mass. If my proton is broken apart, sending the three quarks out to reform or decay, the virtual proton in the Matrix is still the same...unless someone consciously chooses to change it to match the current state of the "real" proton.
Moving on, of course there's nothing that says that the Matrix couldn't become self-aware as a whole...I'm just not seeing it (yet?) in the canon that it is, only that it's like the biosphere and the Resonance is the Astral for the Matrix. But, I'm conservative on this stuff, so I'd say...that's a working analogy and probably riddled with exceptions and inconsistencies.
I agree with your timeline up to, but not including, #3...

--When you put the voltometer to a technomancers head, the reading it gives you is merely a result of the universe attempting to preserve it's self-consistency.
I'm not quite sure what you mean by that statement. For me, it's too "sentient-Universe" for me. If you were to search for wifi signals in a shielded room with a technomancer in it, you "should" see some activity if the technomancer tries to send information...this would preserve "reality" (how the natural laws are known to work), but the Universe doesn't have to "attempt" anything...the laws of nature just "are."
--Very possible that there was technomancy before wireless matrix, but the advent of ubiquitous computing revealed the phenomenon.
It is possible...though I would think that around 2010-2020 (with current tech as it is) someone would have detected microwave/short radio waves being emitted by some humans, but it's possible that it could have slipped through.
--The analogy between magic and technomancy is purely due to the Matrix imitating reality and thus also an Awakened reality. A Matrix developed on some metaplane that had totally different structure of mana flow or of astral plane would have a very different structure of Resonance. for example say I built a Matrix in a meta-plane in which the use of Mana didn't drain you, it actually empowered you. Then in the Matrix developed on this meta-plane, threading and compiling would actually empower you more and wouldn't cause fading.
With the separation of Magic and Machine, I cringe at calling it a metaplane. And the astral metaplanes are too ethereal (hehe) to allow for such a system which needs stability...things get funky when your 0s and 1s start drifting into cats, half-cats, and drop bears. However, the physicist within me says, yells even, "At some level there must be a mana force-carrying particle."
Why is the creation of an analogy to magic at all important? Wouldn't technomancy happen without an Awakening?
--Possible answer: it very well may have, but perhaps the magical analogy helped the matrix "spiritually" become more in-tune with the "place of knowledge" after it became self aware. Maybe the Matrix would have not thought such things as "telepathy" possible had there not been an Awakening. The Awakening opened everyones mind to many new possibilities and maybe it also opened the Matrix's mind. This is almost saying that the whole Matrix became a Shaman or took a Shamanic view of the world. This would also point towards Shamanism being more fundamental than Hermeticism.
In answers to the questions...It's not. Yes, it could, especially if you keep with a separation of magic and machine. And I'd have some really sage-like Resonance researchers/professor types in Shadowrun saying, "Magic has befuddled the issue. Everyone jumps to point at magic now these days as an explanation for everything. Science takes time and in time, with enough research, I'm confident we will find mundane explanations for these so called technomancers."
Hey, but I guess all I'm saying is that this is what my character Jericho would say. This is basically just a more detailed explanation of only one "Stream". Another theory is....it's only a game Inca you geek bastard!!
But such a great game!
