Having a representation of itself doesn't mean it has an awareness of itself.
In your lingo, something can know what it looks like without taking its aspects into consideration.
I think the inverse is true, though: something that cannot perceive a representation of itself cannot be self-aware.
Maybe or maybe not. This is the nub of the debate. I would argue that answering "yes" to this is a partial endorsement of pan-psychism. If the ability to experience qualia is property of certain algorithms or types of information flow then it's a fundemental property of the universe.
Thought experiments about p-zombies and mind simulation are an interesting litmus test to separate different points of view on this.
(sorry) This would mean, at a minimum, that every biological entity down to single cell organisms are conscious. They could be, I don't know.
Everytime you wake up in the morning.
Some work detecting it as well for medical reasons https://www.science.org/doi/10.1126/scitranslmed.3006294
We are biological machines. Sure, we have an awareness of ourselves, but so do computers in some contexts; for example you could argue a certain types of self-modifying or monitoring code has an awareness of itself. It's already been proven that animals have an awareness of themselves when looking in a mirror, such as Dolphins, Chimpanzees, etc. Humans may be a bit further along in our cognitive development but there is no obvious point where you can say "Humans are conscious" because we're all somewhere on a sliding scale of intelligence and self-awareness.
