It's also silly because if it's a gene, then it's just using conventional chemistry to produce an effect. Plants have genes to make chloroplasts that use quantum effects[0] to efficiently do photosynthesis, but nobody is arguing the mechanism is some sort of special woo-woo science. And you can use the same tricks in a machine[1].

Uh, yeah, when photosynthesis was first shown to exploit quantum it was called special woo-woo science. But it just exploits coherence, which is the one thing that seemed within reach of enzymes.
