It is obvious that there are several levels of consciousness. Tononi (I
actually worked in his lab for some time) and Kock have a theory of
consciousness that can actually attribute a number to how much
consciousness there is in a system (of course if you agree on their
definition of consciousness). I think it is one of the best (even if not
complete) approaches to understand scientifically what consciousness is.
According to this theory, consciousness is present in everything even a
rock. It is just the amount of consciousness that matters. By the way, what
they try to calculate is something called Integrated Information which is a
quantity that measures the level of information present and how it is
connected between the parts of the system. Too much connectivity doesn't
seem good for consciousness and too little is also not good. It seems there
is a perfect spot in between that creates the highest level of
consciousness (that the authors equate to this quantity). I don't think a
scalar (a single number) can capture what consciousness means but maybe it
is a good proxy for it and gives us some interesting insights. The beauty
of it is that you can use it to calculate the Integrated Information
indirectly (because it is very complicated to calculate all the connections
in a brain both theoretically and from an experimental point of view). But
you can use proxies like blood flow or EEG activity to measure Integrated
Information indirectly. This quantity is low when measured during sleep as
you would expect, in different states of coma. It has been used to measure
the awareness in patients with locked-in syndrome and establish some
subjects were still aware and then they tried to communicate with them with
Instead of prolonged philosophical discussion this type of research is what
is needed to understand what consciousness is all about.
By the way, I do have a common position with Gordon.
I think there is something special in human-level consciousness. I don't
think consciousness is a continuum. Yes, in theory, we could associate a
value of consciousness to anything but the true consciousness that we
usually refer to is something relatively unique. It is probably something
akin to phase transitions. I'm not sure Integrated Information behaves in
that way where there is room for phase transitions, I need to look into it.
Also, I would like a theory of consciousness that was
multi-dimensional, and maybe a tensor would be a better way to represent it
There are many clues that consciousness comes both as a gradation (think
about what happens when you drink alcohol to the point to passing out) but
also it is phase shift (for example when we go from slow wave sleep and
wake up all of the sudden). Slow wave sleep is an interesting state of the
brain where a lot of things are happening in the brain (making memory long
term, deleting memories we don't need anymore, like my exes) but we are not
aware, in fact, it is very similar to a coma. It turns out that the same
type of brain waves we see in human slow-wave sleep is the type of waves
(in terms of frequencies) in reptiles. Lower forms of animals have lower
brain frequencies and humans have higher gamma frequencies that are not
present in many other animals. There is a lot of evidence that indicates
consciousness is supported by these higher frequencies. I like to think
that a lizard is basically in a slow-wave sleep state even when it is
awake. It is not really conscious and its actions, like responding to the
presence of a mate, running away from danger, and so on are basically
automatic actions that do not require a higher level of consciousness. It
is some form of awareness but I agree with Gordon here, that if we could
find ourself in a lizard brain even for a few seconds we would not
recognize it as consciousness (basically it would feel like we are in deep
Not sure what level of consciousness these AI have but I agree it is not
quite yet human level, maybe they are more in a REM state, they are kind of
