What this article and most others lack is an adult treatment of why serious neuroscientists and philosphers of the mind feel the problem is in fact, hard.
To me, the fact that illusion and hallucination are being invoked is strong evidence of handwaving being engaged in to dismiss an otherwise difficult problem. This is not a scientifically rigorous explanation and it doesn't take the other side seriously.
As a younger guy, I read Dennet and mistook him for a serious thinker. Then I read his rebuttals of his opponents and all he did was accuse them of 'residual christianity' and make profane acrostic poems. These guys just aren't taking the other side seriously and it's kinda silly honestly.
