What is this subjective experience, this awareness of existence, that we call consciousness? In tonight's episode, we will examine some of the aspects of this philosophical, scientific and spiritual question. Is consciousness a binary thing, or is it a kind of continuum with different "levels"? Do animals experience a degree of consciousness and how can it be infered of measured? Is it reductible to biology, is it the product of the treatment of information, is it something immaterial and detached from the physical world? Could an AI acquire consciousness from a silicon substrate, and if yes, what would be the pre-conditions and consequences? These are some of the questions we will try to answer, or at least understand better.
