The hard problem of consciousness is that we can only measure and observe the objective aspects of it. Only the conscious person can observe what it feels like.

When we look at learning systems, we see they are about input, output and feedback. And that our brains learn by predicting the feedback, by modeling the outside world and internal states.

To do so, the brain must be observing itself in two ways:

Our brains are self-observers, why would that not be consciousness? Enriched by all the human aspects, like episodic memory, empathy and love.
