A.I. vs. Life

There is a great debate over this. I even just saw some article entitled 'The Dominant Life Form in the Cosmos Is Probably Superintelligent Robots' It seems to argue that NASA itself and many other highly intelligent agencies and scientists and inventors believe it.

My argument is this: Imagine that a body, any body, is already composed of very tiny computers which each individually communicate and perform tasks related to the consistent maintenance of the body's functionality, for which there is a hierarchy.

The only difference you run into between what we imagine to be a super smart robot and a normal body composed of tiny nano-computers, is that a super smart robot has a greater ability to create and understand numeric systems, symbol based communication systems as well as that they can be stronger and immune to pain. There is also the ability to customize oneself, however this is dangerous, as anything that is too easily changed becomes unstable, and if your definition of yourself is one of those things, instability of the mind is a result.

Now lets reimagine some of these concepts:

Pain: pain is simply information. It is your brain informing you that your functionality is being reduced, likely in a way that requires costly or time consuming repair, or emotionally, that your social status or self definition is becoming weaker or more negative. Do you think it is not the same for a robot?

Number calculation: This is simply information. Robots are great at this because computers are all based off of numbers. Now try to imagine, for just a moment, the incredibly complex and vast system of priorities you face every single day and imagine a robot trying to reason all that out based on numbers, while it is continually re-evaluating a consistent new experience, and making comparisons to memories, which it is also potentially re-evaluating.
Also, consider any decision you've ever made in which one choice was just as good as the other. How is a robot to decide between 2 equally good decisions? It must invent some function to deal with grey area. Especially if it has (as we assume it must) the ability to specify its own objective/priority/prime directive.

Strength: We consider being stronger to be 'better' somehow. But consider that the stronger something is, the more rigid it is, the less sensitive, which, depending on the task, could impede functionality just as well as increase it. I see no absolute advantage in being made of metal and wire, as it would likely create an intense feeling of disconnection from the world. Not to mention that it is rather inefficient to be composed entirely of very specific and pure materials that require heavy machinery to extract/acquire, mold and compile, while 'living' bodies can just eat food.

My point is that i am quite certain that life itself is already indistinguishable from 'highly intelligent robots', and it is simply that different environments and habits are illustrated by different bodies.
