"Attention, and the brain’s internal model or schema of its attentional processes, plays a central role in consciousness, and may explain why people believe consciousness is nonphysical."

No, "people", including many scientists, believe consciousness is "nonphysical", i.e. not explainable with our current set of physical laws and models, simply because it isn't.
Replacing consciousness with a different word ("attention") will not solve this missing link in our current phyisical laws and models.
And the discovery that a well known and widespread mechanism used in modelling, understanding, and controlling *any* type of system (abstraction) is also present in the brain does not bring us any closer in solving the Hard Problem, either.
Lots of abstractions in a self-driving car. But how would you define "attention" in such a system and how would that make it conscious..?
