This is the crux of the disagreement between those that believe AGI is possible and those that don’t. Some are convinced that we “obviously” more than the sum of our parts, and thus an LLM can’t achieve consciousness because it’s missing this magic ingredient, and those that believe consciousness is just an emergent behaviour from a complex device (the brain). And thus we might be able to recreate it simply by scaling the complexity of another system.
Where does the description given imply that consciousness is required in any way?
The fact that there's a non-obvious emergent phenomena which is apparently responsible for your subjective experience, and that it's possible to provide a superficially accurate description of you as a system without referencing that phenomena in any way, is my entire point. The fact that we can provide such a reductive description of LLMs without referencing consciousness has literally no bearing on whether or not they're conscious.
To be clear, I'm not making a claim as to whether they are or aren't, I'm simply pointing out that the argument in the article is fallacious.
