Embarrassingly incompetent article. Given that one can observe up to 40 definitions of consciousness (
https://philpapers.org/rec/VIMMAT - also many definitions are unrelated at all), "consciousness" is almost certainly just a family resemblance category at best, and talk about whether or not something is "conscious" without providing definitions is simply completely unserious.
To make progress, you have to talk about kinds / aspects of consciousness. AI does and will share some of these aspects with humans, but it will not and does not share others. It is really that simple. For the most part, modern AI implemented via LLMs has almost none of the stronger or most core aspects of consciousness.
For huge parts of the article "intelligence" and "consciousness" are conflated, which is mostly extremely unhelpful, as this is not generally a core feature of most aspects of "consciousness".
The moral arguments are also incompetent, i.e. claiming "Moral reasoning is [...] is necessarily subjective" is just clearly empirically wrong, as in fact LLMs can produce moral reasoning (i.e. verbalized moral arguments that are coherent), as can p-zombies (i.e. there is nothing 'necessary', in the philosophical sense of the term, about subjectivity here). The only way the argument holds is if you tautologically define moral reasoning as requiring that reasoning be produced by a consciousness, but this is question-begging.
