The brain-as-computer metaphor shaped modern AI but may be misleading the consciousness debate

Prominent researchers Anil Seth, Ned Block, and Giulio Tononi argue in a Nature commentary that current artificial intelligence lacks consciousness and will not attain it through silicon-based computation. They contend that the prevailing metaphor equating brains to computers is fundamentally limited and warns against attributing sentience to machines. This critique challenges the assumption that consciousness is an inevitable byproduct of processing power, suggesting that biological architecture may be essential for subjective experience.
