No matter how perfectly a silicon-based artificial intelligence mimics the synaptic routing of a human brain, it will never achieve genuine consciousness. Admittedly, many neuroscientists posit that human consciousness arises solely from the complex routing of electrical signals, a view implying that consciousness is entirely substrate-independent. If this structuralist view were accurate, a perfectly mapped silicon replica would indeed generate consciousness. However, recent evidence from quantum biology demonstrates that the specific biochemical material of the brain—specifically, the microtubules within neurons—plays an irreducible role in sustaining conscious states. This confirms that consciousness is inherently tethered to the biological substrate in which it originally emerged.
Which one of the following most accurately describes the role played in the argument by the claim that consciousness is inherently tethered to the biological substrate in which it originally emerged?
- It is an intermediate conclusion that is supported by recent evidence from quantum biology and that in turn provides support for the argument's opening claim.Answer
- BIt is the main conclusion of the argument, which is supported by the claim that silicon-based artificial intelligence will never achieve genuine consciousness.
- CIt is a foundational premise offered to prove that the specific biochemical material of the brain plays an irreducible role in sustaining conscious states.
- DIt is a principle central to the structuralist view of consciousness, which the argument as a whole is designed to reject.
- EIt is provided merely as background information to explain why neuroscientists mistakenly believe that consciousness is substrate-independent.
