He is saying "The AI riskers claim 'If you accept X, then you must accept Y'", where X is "the brain does not use quantum effects" and Y is "AI apocalypse". He does not himself take a position on X, but argues against the X=>Y implication. And it's not really relevant, but for what it's worth, the majority consensus among neuroscientists is that the brain does not use quantum mechanical effects and can be modeled using classical physics alone. Roger Penrose is in the minority on this question.
