Although it would be very interesting if we could hijack an optic nerve stream, calibrate it using a test image, and then attempt to recreate the visual processing units. Unfortunately this falls prey to the same fundamental problems in some ways - we will only be able to interpret the signal of a mouse or cat in a way that we understand. That is, we would attempt to recreate a signal that is coherent to us and makes sense to our visual system, but that isn't really representative of their actual visual experience.
I face this issue a lot too as a writer who has to take on complex science and make it understandable to a broader audience - something like quantum computing, for instance, or solar concentrator efficiency. It's difficult! And sometimes the details have to take a back seat. But with a lot of vision and cognition stuff I feel that fundamental concepts go by the wayside in order to make it more easily digestible. I think many people could stand and might appreciate taking it to the next level.
