I think what makes it tricky for me is I agree with _some of_ what I see so far from Donald Hoffman already; our experience of reality is constructed by our senses which, along with our brains have evolved to best take advantage of environmental affordances for our survival and thriving. I also agree that there’s nothing that guarantees truth value based upon correspondence to sensory data and reason.
But it is another thing to say “it is all illusion”. If you study the mechanisms of the eye and ear and touch and how they function; we can measure them like we might machines. We can create machines out of other materials to achieve lesser forms of human senses and cognitive functioning; our mathematics and computer systems and scientific processes are all based upon lesser versions of human cognitive function; the creations are necessarily less in some fashion than that which created them.
