Those are both examples of signals we can't interpret interfering with the signal we're trying to interpret.

However, it's not like the electrical noise came to be by magic -- it's the result of many interactions that have a structure, and hence impart that structure on the "noise", we just lack key facts to be able to interpret that signal.

Your example of lack of structure, rather than merely something we can't interpret, is algorithmically generated?

I think we may be speaking past each other.
