My model of abstraction is that high-level abstractions summarize all the information from some chunk of the world which is relevant “far away”. Part of that idea is that, as we “move away” from the information-source, most information is either quickly wiped out by noise, or faithfully transmitted far away. The information which is faithfully transmitted will usually be present across many different channels; that’s the main reason it’s not wiped out by noise in the first place. Obviously this is not something which necessarily applies to all possible systems, but intuitively it seems like it should apply to most systems most of the time: information which is not duplicated across multiple channels is easily wiped out by noise.
