Great essay writing, nice flow. You captured my attention with your storytelling.
But when you get to the point where you state "What does that mean? Perhaps the real world isn't particles and waves, but information—quantum information—in all living processes.", you lose me with the sudden introduction of quantum information.
--> How does quantum information relate to the previously described action of the wave function of the photon in the leaf?
"Today, the "quantum garden" metaphor can perhaps take us to the most primitive structure of the universe."
--> I like your quantum garden metaphor, but I would like to have seen some more elaboration on the metaphysics of entanglement and the structure of the universe in space and time as you see it, as you say "entanglement suggests the universe is one web of connection where distance is relative and all things are connected."
--> You can state this, but I would like to know how you see this yourself, before I have to believe the truth of your vision. If you cannot see it, how am I supposed to see it?
All-in-all very poetic, but I am missing the plot and some elaboration. But it was pleasant to read.
