I build robots as a hobby. My robots are aware of their their environment and their place in it. In that sense, they're "self-aware" but nobody would argue they're conscious.

The underlying problem is that we have all these words that imply a precision that doesn't exist. All we can say for certain is that consciousness and self-awareness are effects we experience. Beyond that, all bets are off. We can't even really say what these things actually are.
