Machine Consciousness

The Holy Grail of Artificial Intelligence

The provided lecture notes explore the philosophical and scientific debate surrounding the possibility of conscious machines.

We will discuss functionalism, a theory proposing that mental states are defined by their causal roles, arguing whether this implies that consciousness is exportable to non-biological systems.

We will also examine the nature of qualia, subjective experiences, questioning whether they can be reduced to functional processes or if they represent an irreducibly subjective aspect of consciousness.

The role of sensory-motor skills and the limitations of the computational model of the brain are also explored, challenging the prevailing information-processing metaphor for understanding human intelligence and consciousness.

Finally, we present various perspectives on the criteria for attributing mind and consciousness, including first-person experience and third-person observable behavior, highlighting the complexities and ongoing uncertainties in this field.
