We are constantly fed a version of AI that looks, sounds and acts suspiciously like us. It speaks in polished sentences, mimics emotions, expresses curiosity, claims to feel compassion, even dabbles in what it calls creativity.
But what we call AI today is nothing more than a statistical machine: a digital parrot regurgitating patterns mined from oceans of human data (the situation hasn’t changed much since it was discussed here five years ago). When it writes an answer to a question, it literally just guesses which letter and word will come next in a sequence – based on the data it’s been trained on.
This means AI has no understanding. No consciousness. No knowledge in any real, human sense. Just pure probability-driven, engineered brilliance — nothing more, and nothing less.
So why is a real “thinking” AI likely impossible? Because it’s bodiless. It has no senses, no flesh, no nerves, no pain, no pleasure. It doesn’t hunger, desire or fear. And because there is no cognition — not a shred — there’s a fundamental gap between the data it consumes (data born out of human feelings and experience) and what it can do with them.
Philosopher David Chalmers calls the mysterious mechanism underlying the relationship between our physical body and consciousness the “hard problem of consciousness”. Eminent scientists have recently hypothesised that consciousness actually emerges from the integration of internal, mental states with sensory representations (such as changes in heart rate, sweating and much more).
Given the paramount importance of the human senses and emotion for consciousness to “happen”, there is a profound and probably irreconcilable disconnect between general AI, the machine, and consciousness, a human phenomenon.
I haven’t noticed this behavior coming from scientists particularly frequently - the ones I’ve talked to generally accept that consciousness is somehow the product of the human brain, the human brain is performing computation and obeys physical law, and therefore every aspect of the human brain, including the currently unknown mechanism that creates consciousness, can in principle be modeled arbitrarily accurately using a computer. They see this as fairly straightforward, but they have no desire to convince the public of it.
This does lead to some counterintuitive results. If you have a digital AI, does a stored copy of it have subjective experience despite the fact that its state is not changing over time? If not, does a series of stored copies representing, losslessly, a series of consecutive states of that AI? If not, does a computer currently in one of those states and awaiting an instruction to either compute the next state or load it from the series of stored copies? If not (or if the answer depends on whether it computes the state or loads it) then is the presence or absence of subjective experience determined by factors outside the simulation, e.g. something supernatural from the perspective of the AI? I don’t think such speculation is useful except as entertainment - we simply don’t know enough yet to even ask the right questions, let alone answer them.
I am more talking about listening to and reading scientists in media. The definition of consciousness is vague at best
