Dear Sir,
You have correctly pointed out that the material world isn't anything but the information we can collect about it. But when you say only the information is foundational, you are really applying the Occam's razor and throwing the baby with the bath water. Information can be only about some observable. If there is no observable, there cannot be information. The observable is the "storage" of information and observation is the "processing unit" that decomposes information into various types of stimuli - sound waves for auditory perception, electromagnetic waves for ocular perception, gravitational waves for tactile perception, etc. And information is nothing but a composite of these individual perceptions. If it can't be perceived, it is not information. Electrons and protons display specific behavior, the reporting of witch is the information. Information does not induce specific behavior in them, but only reports it.
There are two types of physical effect: the first due to time evolution due to perpetual motion (cause and effect) and the second due to application of force by a conscious agent. Information is relevant for the first type of effect except providing data for use by a conscious agent (computer according to you). In the second case, if the local equilibrium has been disturbed inducing the conscious agent to restore it, then information determines his reaction (processing according to you). You have not elaborated further even though there was no space constraint, but advised to purchase your book. Unless you create interest in the subject by a brief summary, no one will be interested to purchase your book. Thus, your essay remains incomplete.
All along you have used terms like "current information", "previous information", etc., without defining what is information. The computer does not function naturally, but we design and write the algorithm for the computer to function. Hence it will be a creature of our ideas and limitations - GIGO - garbage in, garbage out. The notion of Information cannot become the new big paradigm for Physics.
