Not necessarily. I think that a robot could be programmed to simulate goals or to avoid goals entirely, both with equal chance of success. A robot could be programmed to imitate the behaviors of others in their environment. Even in the case where a robot would naturally accumulate goal-like circuits, there is no reason to presume that there is any binding of those circuits into an overall goal. What we think of as a robot could just as easily be thousands of unrelated sub-units, just as a person with multiple personalities could navigate a single life if each personality handed off information to the next personality. > It has complex systems and subsystems that may have conflicting subgoals, > and in order to learn from experience it keeps a narrative history about > what it considers significant events. > We don't know that there is any such thing as 'it' though. To me it's seems more likely to me that assuming such a unified and intentional presence is 1) succumbing to the pathetic fallacy, and 2) begging the question. It is to say "We know that robots must be alive because otherwise they would not be as happy as we know they are." > At that level it may have the consciousness of a mouse.

Machines need not have any kind of model or self-image which is experienced in any way. It doesn't necessarily appear like 'Field of Dreams'. What is needed is simply a complex tree of unconscious logical relations. There is no image or model, only records which are compressed to the point of arithmetic generalization - this is the opposite of any kind of aesthetic presence (qualia). If that were not the case, we wouldn't need sense organs, we would simply collect data in its native form, compress it quantitatively, and execute reactions against it with Bayesian regressions.

If you turn that assumption upside down, and instead begin from the position that the definition of genuine cannot be doubted to begin with, and that qualia is already understood far more than we could ever understand anything in physics, then the proposition that understanding qualia as well as we understand electrodynamics becomes absurd, since our understanding of electrodynamics is itself robotic. To get at the nature of qualia and quanta requires stripping down the whole of nature to Absolute fundamentals - beyond language and beyond measurement. We must question sense itself, and we must rehabilitate our worldview with ourselves inside of it, not just the cells of our brain or the mechanics of our evolved behavior in the world. The toy model of consciousness that modal logic and computation deliver is a good start in the wrong direction. To progress beyond that I think requires the greatest 180 since Galileo.
