[guerrilla]

Either it's inane wordplay or it's obviously nonsense for most definitions of conscious. An illusion must be perceived, so in that sense the proposition is self-refuting. Also, you have empirical evidence against it: you know when you're conscious and that sometimes you aren't (and that it's a spectrum.) Thirdly, you can behaviorally define conscious. Fourthly, if I'm not mistaken, you can measure its presence neurologically. To say that all of this is an illusion is stupidity or being very obtuse for attention (like clickbait.)
