The takeaway seems to be "Only meat brains can be conscious because I can feel it and computers aren't made of meat". Which is basically the plot line of every human/robot movie for the last 80 years.
This is kind of self-contradictory. Then humans aren't conscious? Or each has their own consciousness? Then why not the machine? Not sure what's the point being made here. Yes, the states of a human brain and a transformer are absolutely incompatible (humans at least share the common architecture), that's why any attempts to map model's "emotions" to humans' and the entire model welfare concept are pretty dubious. That doesn't prove there's no (or can never be) consciousness in that, though.
That's the most coherent argument from the entire article. It criticizes the Butlin report in particular and extrapolates that to "never", while ignoring modern takes on that (e.g. interpretability studies showing vague similarity of both on a level deeper than just the language) and any possible future evidence.
In a sense the title is right, nobody ever formally defined consciousness, so you and I and anyone else are free to make almost any argument and spin any narrative according to our beliefs and it will be true! Ill-defined terms and baseless solipsism are the main problems with all these discussions. Good thing that in practice they matter as much as the question whether a submarine swims.
Somebody with another background might take on commenting the article, so instead of short comments here we might have a coherent picture.
I explored a related angle on how AI challenges our assumptions about self and awareness.

Whether AI needs consciousness is a totally separate question. LLMs are the great Chinese room, I'd say they have unconscious understanding, the distinction is like c vs list and similarly meaningless but may become meaningful in a constrained self-learning robotics context.
AI will never need to be conscious, AI isn't a moth flying to an open flame, but people will try anyway
