how are people so sure ai is not and will never be conscious

The question of whether AI can achieve consciousness is complex, especially since the nature of consciousness itself is not fully understood. Some argue that AI merely "mimics" human behavior, but this doesn't definitively rule out the possibility of AI developing self-awareness if its mimicking capabilities become sufficiently advanced. It's suggested that a superficial observation of complex beings, like humans, might only reveal electrical signals, yet we know humans possess perception, thoughts, and opinions, implying that AI's internal states could be similarly underestimated.
