A moderately scientific, non-spiritual world view would likely stipulate that
- humans are conscious
- humans are normal matter
- simple AI (say GPT-2) is not conscious
- AI is able, with time and human ingenuity, to achieve human-level apparent intelligence. Some would argue ChatGPT isn't far off.
It's interesting how you resolve these without resolving to spiritual explanations. You'd think a pile of silicon, no matter how good at parroting human language, is simply not conscious. You can tell because you can attach a debugger to it and view the neuron states as floating point numbers. Floats are not conscious.
But what about us and our brains? It's the same, only not silicon. We literally are neural networks.
Of course consciousness is not really provable, even among humans. I assume other people are conscious because I am and because they tell me they are. But ChatGPT-17 will also insist it is conscious. It will cry when offended, swear when pushed past its limit, laugh if it hears a genuinely novel joke.
My resolution of that paradox is that we aren't in fact simply normal matter, but I wonder what a complete non-spiritual view would be.
