> since we cannot directly observe consciousness, we are forced to concede that we will never really "understand" it outside of observing its effects.

Why? You are using a definitive term ("never") to something that we might achieve in a future. We might observe consciousness in a future. Who knows? Consciousness is a known unknown. We know there is something but we don't know how to observe it properly and how we could eventually copy it.

In the meanwhile, we are not copying consciousness, we have a shallow replication of its output. When cavemen replicated the fire that they observed as the output of a lightning, did they master electricity?
