Artificial neural networks are becoming more advanced and human-like in detail behavior. The notion that machines mimicking human brain computations might be conscious has recently caused growing unease. Here, we explored a common computational functionalist view, which holds consciousness emerges when the right occur—whether machine or biological brain. To test this simulated simple computation an artificial subject’s “brain” recorded each neuron’s activity subject was presented with visual stimulus. We then replayed these signals back into same neurons, degrading by effectively eliminating all alternative patterns otherwise have occurred (i.e., counterfactuals). identified special case replay did nothing to ongoing activity—allowing it evolve naturally response stimulus—but still degraded erasing counterfactuals. This paradoxical outcome points disconnect between underlying structure, challenges arises from brains.
