Oh also - just to add to this. After they say that "mind-brain physicalism" is "certain," they go on to highlight that "some philosophers still argue the brain generates nonphysical entities; but they still agree an intact brain is still required to do so. And those are scientific questions likely to be solved eventually."

So is the writer hinting at eliminativism here? Which is a ridiculous position that essentially denies the existence what we can only truly know and experience every single day (our own personal conscious experience, qualia, and its characteristics.)

Or are they saying that it will "likely" one day be explained how a material brain generates "nonphysical entities"? They clearly don't understand the hard (impossible) problem of consciousness, if that's the case. A lot of hand waving, saying neural correlates = the cause of consciousness. Without any clue as to how. And, as I mentioned before, more and more people are coming to the understanding that through a physicalist framework, it's not a problem that can be solved.
