Thank you Casper for this crystal clear. A few years I wrote this article called "Quantum Vinaigrette" (https://medium.com/@noubel/does-quantum-physics-explain-consciousness-2e591274df29) that goes in the same direction.
As a researcher working on consciousness and intelligence, I see the separation between subject and object as a transition state in the growth of consciousness. One needs first to separate reality between "subjective" and "objective" before he.she can reach the next stage that you describe, as a deep embodied experience and not just a philosophical debate. It shows the evolutionary shift from prerational to rational to transrational.
