@Elena I think we need to understand more about our brains. 

if you ask Siri if she's self-aware or not, she says "Are you?" :"D 

so if we can't prove that we are self-aware, how will we know if an AI is..  

Do you think if they become more intelligent (in which they will) and self-aware as well that they will want to control us?

Can it achieve either of them?

As I understand, consciousness is the perception of your surroundings. And self-awareness is realizing your own character or feeling
