That's not a good comparison because the universal computation is actually much more powerful and beautiful than a pile of rocks in a washing machine.

What's the bastardized definition that you're talking about?

Again that is 'information' in the same way the distance and angle between my washing-machine rocks are at any given moment. We could even find a way to control the direction a predesignated face of the rock is pointing and do computations with it.
That's a part of the definition but not the whole thing, because you didn't take into consideration the fact that the position and velocity of the rocks will change from one moment to the next inside the washing machine according to the laws of physics. The washing machine is the computer, the rocks are the input, and the laws of physics are the program. In this sense, by merely existing and evolving in time, any physical system, whether it's a washing machine or not, transforms or processes that information in a systematic fashion. That's what it means to process the information.
Also, information is more fundamental than matter and energy because energy is the ability for physical systems to do work whereas information is telling the physical systems what to do. Hence Wheeler's phrase "it from bit," which he summarizes the meaning in the following words:
"It from bit. Otherwise put, every 'it' - every particle, every field of force, even the space-time continuum itself - derives its function, its meaning, its very existence entirely - even if in some contexts indirectly - from the apparatus-elicited answers to yes-or-no questions, binary choices, bits. 'It from bit' symbolizes the idea that every item of the physical world has at bottom - a very deep bottom, in most instances - an immaterial source and explanation; that which we call reality arises in the last analysis from the posing of yes–no questions and the registering of equipment-evoked responses; in short, that all things physical are information-theoretic in origin and that this is a participatory universe." (John Archibald Wheeler 1990: 5)

Thanks, but wasn't that an argument-from-authority fallacy again (as you told me before several times)? ... or ... did I just get better at it somehow?
