Dear discussants,
I tend to disagree with the motto "information is physical" if taken too
strictly. Obviously if we look "downwards" it is OK, but in the "upward"
direction it is different. Info is not only physical then, and the
dimension of self-construction along the realization of life cycle has
to be entered. Then the signal, the info, has "content" and "meaning".
Otherwise if we insist only in the physical downward dimension we have
just conventional computing/ info processing. My opinion is that the
notion of absence is crucial for advancing in the upward, but useless in
the downward.
By the way, I already wrote about info and the absence theme in a 1994
or 1995 paper in BioSystems...
best

Thanks John and Kevin to update issues in information, computation,
energy and reality.
I would like point out to other articles more focused in how
coherence and entanglement are used by living systems (far from
thermal equilibrium):
