The consciousness is a complicated concept to define but an international team of neuroscientists has made a solid attempt to do just that, define what exactly consciousness and determine whether we are near the holy grail of Artificial Intelligence: AI self – conscious.
The short answer to this – nothing new – approach is… no. But, before we regret, the experts do explain how we could build fully conscious minds.
We have two ways of raising awareness, in a simple way and a complicated one. The simple form is difficult, so the complex, imagine how it should be (having to define characteristics as important as free will). Despite this, we could say that consciousness is the thoughts and sensations that we all experience individually.
Assuming that consciousness itself is based on the physical laws described in physics and chemistry, we should be able to find a way to chisel or compose it. This was one of the dreams of the scientist Alan Turing – who wanted to achieve a machine that imitated the human brain – that today would be impressed by the level of artificial intelligence that Google’s AlphaGo Zero has demonstrated, for example.
However extraordinary these AIs may be, they can solve problems at unusual speeds, however, they still do not know they can solve problems. How to make ‘wake up’?
Three types of consciousness
Scientists who published their study in the journal Science divided consciousness into three categories: they called the lowest category C0, equating it with solving problems that our brains do without our conscience, like driving home from work almost without giving account. In the case of computers, the example would be the vehicle without a driver, a consciousness that, therefore, already dominate.
The next category is C1.“It refers to the relationship between a cognitive system and a specific object of thought, such as a mental representation of” the light of the fuel tank, “the researchers write: In C1, that object of thought is selected for global processing, moving it From a close relationship to one that can be manipulated in several contexts, the
last category is C2, which acts as a supervisor who observes consciously the tasks at hand, encompassing what we call ‘metacognition’: a feeling of knowing what we know It is also known as “theory of mind .”
Consciousness C1 can occur without C2, and vice versa, but, according to experts, none of the systems has an equivalent in artificial intelligence, not yet at least.
The researchers speculate that C1 evolved as a way to break the modularity of unconscious processes.
Recent advances in microchips that can store and process information as if it were neurons, could play a key role in the revolution of existing modular technology.
To put it to work, we would need to learn more about how our own brains create their own global workspace, an architecture that gives rise to what we consider our consciousness.
To develop this C2 technology, researchers suggest several processes, such as some that apply probability to decision-making, and others that have some kind of meta-memory to establish a line between what is known and what is not. So we could build in the future, conscious machines based on our own mental ‘hardware’.
