I mean. You could write program with a "mind" object that recieves a bunch of data through various sensory "experience". From the perspective of the "mind", the data is "subjective", and the mind is "implemented" in exactly a way that it can represent itself as an entity "I".
I don't think the biological reality is conceptually any more complicated, except that the mind and data are complex in exactly a way that completely hides the abstraction, roughly by being very good at ignoring meaningless artifacts of abstraction.
The hard part isn't imagining such a subjectivity, but imagining that I am that.
But, where does the color red come from? The actual first person experience of seeing red. Not eyes seeing a specific wavelength, but your mind seeing red.
What I find so frustrating in these conversations is exactly this mismatch. There's nothing special about the wavelength that creates the color red, but the color red is completely distinct from that. They're barely even related!
