Glad you brought up the word analog. Analog systems cannot be reduced to information, due to complexity, butterfly effect, and all that. We can model them, make many useful short term predictions, but they always drift away from prediction.

I don't think this is generally true, and in any case the distinction between analog and digital is essentially superficial. In fact, all analog systems are representable with full information fidelity on digital systems. A point that escapes most people is that analog and digital are merely coding formats for information in a carrier, but people have taken them to mean something else due to historical precedent in usage rather than fact.

Simply not true. Ever hear of the three body problem? If your assertion were true, the orbits of the various members of the solar system could be represented digitally and everything predicted perfectly. No wondering about the appearance of comets, etc. And the weather could be predicted.

Not only is it impractical to make perfect digital representations of complex systems, it is theoretical impossible.

I prefer digital audio to vinyl, but not to a live performance with acoustic instruments.
