Many computer scientists think that consciousness involves two stages: 1 – accepting new information, storing and retrieving old information, and 2 – cognitive processing of all that information into perceptions and actions. If that’s right, then one day machines will become conscious. That view has recently gained some significant support. In October 2017 Drs. Stanislas Dehaene, Hakwan Lau and Sid Kouider from Collège de France in Paris came to a conclusion that consciousness is “a multi-layered construct. As they see it, there are two kinds of consciousness, which they call ‘dimensions C1 and C2. Both dimensions are necessary for a conscious mind, but one can exist without the other:

  1. Subconsiousness – dimension C1, containing information and the huge range of processes with the required algorithms in the brain where most human intelligence lies. That is what enables us to choose a chess move, or spot a face without really knowing how we did it. The researchers believe that this type of consciousness has already been represented in a digital form and is comparable to the kind of processing that lies behind AI algorithms that are embedded in DeepMind’s AlphaGo or Chinese Face++.
  2. Actual consciousness – dimension C2 containing and monitoring information about oneself, which splits it into two distinct types and which is not yet present in machine learning:
    • The ability to maintain a huge range of thoughts at once, all accessible to other parts of the brain, making abilities like long-term planning possible. In this area there is already some progress. For example, in 2016, DeepMind developed a deep-learning system that can keep some data on hand for the use by an algorithm when it contemplates its next step. This could be the beginning toward global information availability.
    • The ability to obtain and process information about ourselves, which allows us to do things like reflect on mistakes.

This proposition closely correlates well with a theory that Actual Consciousness (C2) is driven by billions of networks that bind together information from Subconsiousness (C1) following stochastic probability similar or identical with the principles of quantum mechanics (Stanislas Dehaene, 2017).

Should those recent findings and proposals from Collège de France in Paris become generally accepted then that might resolve the questions posed by Roger Penrose about the nature of consciousness. He may be right that consciousness is not just the brain-mind construct but is also underpinned by phenomena similar to those present in quantum mechanics, however not in the way he suggests, i.e. in the ‘hardware’ (microtubules). The quantum mechanics’ Uncertainty Principle would not act at the level of individual synapses but rather at the level of neural networks, which connect thousands of synapses and give an averaged response at a macro-level, e.g. lifting a hand. Since that response would be only probabilistic and not based on yes-no state of an individual synapse (and hence its similarity to quantum phenomena), it will ensure that there will be no conflict with the preservation of free will. That might also be in line with the thinking of people like Raymond Tallis, who so strongly defends the validity of free will (i.e. unpredictability of human actions). And that’s how the scientific world may slowly be arriving at some common understanding on the nature of consciousness, and by extension, the feasibility of uploading a human mind together with its consciousness to Superintelligent being.

Let me now summarize the conclusions about the nature of consciousness, as far as science seems to indicate and the consequences for uploading a human mind to Superintelligence. Consciousness is probably one of the very few areas in science where the academics cannot agree on the meaning of the subject they are studying. Probably, and this is still only probably, the human consciousness multi-layered structure and organization has been best summed up in the recent research by the academics from Collège de France (Stanislas Dehaene, 2017):

Consciousness is a structural (functional) organization of a physical system, which operates at two levels: 1. Subconsiousness – accepting, storing and retrieving information using huge range of processes with the required algorithms – this is where most of human intelligence and knowledge lie. 2 – Actual consciousness containing information about oneself, which it turns into a wide range of ‘thoughts’, all accessible at once to all parts of the brain, which it is able to have continually monitored and processed, outputting them as perceptions and actions.”

The above information can be converted into a diagram below:

Such an approach to the nature of consciousness provides a clearer view on a number of questions in this area. For example, it allows for a gradual development of consciousness over millennia of life’s evolution, which might have started with automatic, chemistry based responses, in plants ‘seeking’ best nutrients, i.e. being somewhat aware of the environment. In the animal world the level of self-awareness would be directly correlated with the brain size relative to the body mass and complexity of neural connections. When these two parameters reached a tipping point, human consciousness was ignited in Homo sapiens and other humanoids, such as in the Neanderthal Man. If we accept this notion, then human consciousness, having physical strata and differing only from animal self-awareness because of a much higher level of complexity and self-organization of billions of stimuli and memory cells, can be replicated in a different than a biological strata, such as in ‘silicone’.

Therefore, the main assumption taken here is that once Superintelligence emerges, it will be possible that at some stage it will become a conscious agent.
