...say we build/grow an AI system that passes the Turing test. We talk to it, it comes across as plausibly human.
How do we know we've created something with consciousness, and not just a very sophisticated program? The philosophy you disparage already has a term for this: the "philosophical zombie". For all intents and purposes, they appear human, but they have no internal experience whatsoever. All you'll have done is shunt the problem downstream.
Also, you're wrong about early vision. That's the best studied part of the brain, and in fact, researchers have applied ML techniques to fMRI data and extracted out the images being shown.
