Vladimir,
Your essay is very cogent and insightful, but I still have a problem with the conclusion, one which goes to the nature of the contest question in the first place. I suppose I did not make clear enough that while I paraphrased Marshall McLuhan's equating the medium with the message, I do not agree with it. To me, medium and message are a dichotomy, so to say one is the other would be like saying up=down, or good=bad, or left=right, or night=day. Or more related to the nature of this contest, that node=network.
If I was to paraphrase your conclusion, to make it work for me, I would say, It=Qubits. Remember a qubit simply does not exist, distinct from context.
If I was to paraphrase MuLuhan's quote, I would say; The medium is the message of the previous medium. Much as children are the message of the parents and medium to their children.
In my essay, I didn't say the energy is both medium and message, but that energy is the medium and information is the message.
The problem this raises with the contest question; It from Bit, or Bit from It, is that "it," the "reality," is both information and energy, message and medium, yet "bit" is just information. There is no message without a medium to convey it, as I argued in my essay. Like a dimensionless point, even mathematically it doesn't exist, because it is a multiple of zero. So just like an infinite series of dimensionless points will never add up to a line, since even infinity multiplied by zero is still zero, a reality composed of some platonic realm of information does not physically exist.
So there is no "It from Bit" and "Bit from It" is just the static (in)formation of dynamic processes.
The problem I have with Planck lengths is they are inherently fuzzy, as any further defining distinction would have to be even smaller, thus refuting the premise of "smallest." It goes to the problem of the aforementioned "dimensionless points." We want absolute clarity, but absolute and distinction are contradictory concepts, as at the level of the absolute, there is no distinction. Which is another reason for accepting fuzziness as inherent when trying to make distinctions.
