Sir Roger Penrose - a world-class physicist - still thinks that consciousness is caused by quantum gravity. I expect that no one ever warned him against mysterious answers to mysterious questions - only told him his hypotheses needed to be falsifiable and have empirical consequences. Just like Eliezer18.

There's nothing wrong with proposing the hypothesis. The problem is believing and supporting it while it's pending. That it hasn't been refuted yet is no reason to take that side of the issue. (Arguably it has been refuted, because there are known criticism of it which no one has answered, but never mind that.)

Similarly, discarding other open/pending hypotheses because, what, he *likes* this one? That's obviously unreasonable.
