As soon as we'll have sufficiently advanced BMIs the so called hard problem will go away by itself.
Consider probing a midlevel mobile phone at some hundred contacts. You might be convinced to have a thorough account of the physical reality yet still no idea of (and no way to know) whats going on.
To the problem of qualia.. I think it's the mechanism of the brain to default-name recurring patterns, being part of a simplification/compression process, without which reasoning (computing) or reasonably storing experiences would be impossible. I guess visual qualia like color and shape have to be the first things the brain learns and attaches "default" symbols to. Consider other basic qualia too, like to be saturated, to feel warm and then higher qualia that build on these like to feel loved or accepted in a social community.
It's difficult to argue how there could be a fundamental truth to qualia. But consider that there'd be no difference in our communication, even if your red is attached to a symbol signified by 8NCYUW6D0H5C (lets just assume this) while my red is encoded as being GAUTP1P6YUUZ (those patterns obviously have to be encoded as frequency patterns as we perceive close colors as similar without computational overhead). Eventually it will turn out, qualia from person to person are encoded quite similar, as we are genetically so similar. But consider also synaesthetia. Wrt animals, it WOULD feel strange to be a bat or any other animal as some of their sensory apparatus is so different.
To this, author makes a good point: "Today, we do not have an exhaustive external account, but this is not the same as having proof that no such account is possible."
I imagine consciousness as 'theater mode' of the perceiving mind. As such it seems to be one part of the brain that integrates all sensory inputs into one Multimodal Experience Stream™.
As to TFA.. - I'm by no means up to date to the current affairs of the consciousness debate, but - is there really a "fierce debate [...] raging"?
Check out Joscha Bach who argues consciousness is an illusion. Looking for some material to back up, I hit on this text. Flying over it I already find it more enlightening than the posted article, so I post it here (without guarantee):

Some (citated) citations from it:
"The simulation becomes “more real than real” in our experience because it constitutes the entirety of our conscious access to ourselves and the world (Metzinger, 2003; Seth, 2021)."
"This perspective doesn’t diminish the richness or importance of conscious experience. On the contrary, it highlights the remarkable complexity and sophistication of the processes that generate our subjective experience. The constructed nature of consciousness isn’t a defect or limitation but a remarkable achievement — a way of making an unimaginably complex reality manageable for finite cognitive systems (Clark, 2016; Dennett, 2017)."
