I am not aware of any proof that "Consiousness is a emerging feature of our brains complexity". For all that I know throwing around such statements of truth is mere stupidity and anti scientific
Funny that you go the 'anti scientific' route while proposing a person who also doesn't have proof of his ideas/theory
"While the emergence of consciousness from brain dynamics is commonly accepted" https://www.researchgate.net/figure/Phenomenal-consciousness...
"Consciousness as an Emergent Phenomenon: A Tale of Different Levels of Description" https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7597170/
The way this dude throws around quantum and co is just esotherical.
