Question: Where's Sophia along the “spectrum of consciousness”?
Because “consciousness” is the term that has varied meanings for different people (1-9), the answer depends on how it is defined in this question. However, as this is a philosophy forum, I take it that “consciousness” in this question means awareness that has awareness of phenomenal characteristics occurring, because the problems of why and how awareness of phenomenal characteristics occur are very important in philosophy.
In being aware of anything, such as the red color, there can be two kinds of awareness occurring. The first one is the awareness of that thing’s occurrence and of that thing’s physical characteristics (such as the awareness of the red color’s occurrence and of the red color’s physical characteristics, i.e., the values of its frequency, intensity, saturation, etc.). The second one is the awareness of the phenomenal characteristics of that thing (such as the awareness of the phenomenal characteristics of the red color, i.e., the awareness of what the red color is like in our mind). To be conscious of the red color, the second kind of awareness must occur; otherwise, it will be only unconscious awareness of the red color. It is important to note that the first kind of awareness can occur without the second kind of awareness, and it occurs ubiquitously all the time. We are unconsciously aware of the levels of blood sodium, sugar, hormones, etc. and unconsciously react to them continually, but we never have the awareness of what it is like to have these substances at various levels.
Now, take the red color as an example, computers or robots nowadays have circuits that are built to acknowledge the occurrence and the physical information (the value of the frequency, intensity, saturation, etc.) of the red color, and they can use the information to do whatever they have been programmed to do (e.g. create the red color dots on the monitor, print or speak out “red”, or trigger some other processes). We do not know whether there are qualia (phenomena with phenomenal characteristics) of the red color occurring in their circuits while they are seeing the red color or not (in comparison, we do have qualia occurring in our neural circuits while we are seeing the red color). But if there are qualia occurring in their circuits, computers and robots definitely do not and cannot acknowledge the qualia. This is because there are no circuits built to do this function. All their circuits are built to do something else, such as the summation of two digits, the computation of transcendental functions of some digits, and the generation of signals to control other parts: screen monitor, disc drive, mechanical motor, etc. None is built to be aware of and experience qualia that may occur in their circuits. We, their creators, do not know yet how to build such circuits.
Therefore, without such circuits, there will be no awareness of the second kind (the awareness of phenomenal characteristics) occurring in their systems. All bits of data in their systems will be found to contain information of only what their circuits are built for, which is the information about the first kind of awareness (e.g., the information about the red color’s occurrence and its physical characteristics, and the subsequent processed information) only. No bits of data in their systems will represent the information of the second kind of awareness (i.e., the awareness of the phenomenal characteristics). Consequently, no bits of data in their systems will represent conscious awareness, and consciousness (as defined above) cannot and do not occur in their systems, at least not digitally.
(Adapted from 6.6.2. Do computers and robots have consciousness?)
So, by the definition of “consciousness” above, Sophia is still at the zero end of consciousness, that is she has no consciousness at all.
It is important to note that the answer can be different if the definition of consciousness is not the same as the one in this answer. For example, if “consciousness” is defined to be a command center or a workspace that integrates other mental processes and enables them to function together coherently, such as in the Global Workspace theory
(10) and the Global Neuronal Workspace theory (11), then Sophia has consciousness because she has this kind of command center.
Also, one may argue that Sophia might have a kind of consciousness that is not digitized in her electronic system, so there are no bits of data in her system that represent her consciousness. If so, because it is not digitized, then her consciousness not only cannot be proved to exist but also cannot have effects on her electronic system. Physically, such a proposition is thus null.
