Do We Know What Consciousness Is?

We don't even know what consciousness is yet, right? Or I don't know if we ever will. One of the main things that you want to grab are your photos because those are irreplaceable. So at what point do computers or systems that can augment memory or reality or whatever, what point can we say that they have a consciousness or do they already, right? That's maybe that's a question for another thing, but since you're a computer, you know, whiz and founder, I thought I'd throw that at you.
