Re: I don't understand.
"Inherent" in these arguments is a tell for magical thinking - specifically, the belief that nothing made or modelled in mere silicon can ever match the mysterious working of the human mind. Because - why, exactly?
If you really understand how the human mind works, then what's to stop someone, somewhere, from encoding that understanding?
If, as seems more likely, you would admit that your understanding of the mind is imperfect and incomplete, then how do you know that hardware and software can't (ever) replicate it?
Bonus points if you can define either "understanding" or "consciousness" in a generalised and non-circular form.
