"Coltan is a very essential metal in the creating of capacitors(something I didn't know) so I believe it isn't about it being a bar so early. More likely she is human. What? My reasoning is that her showing greed(taking it for herself rather than letting it fall into the sea) is a showing of her humanness."

"She's a Terminator. Not sure why you thought she was a human. :)

It's not a sign of humanity. Just pragmatism. It isn't like they're trying to wipe out the entire world's supply of the stuff, just prevent it being stockpiled in a designated location."

""Not like" the others could have applied to the T-1000 and T-X, too. And the oldest models could have been capable of eating food. We don't know.

Colten is merely a key component in the ALLOY needed to make Terminator frames. It's just one ingredient, that would be all. It might be less of 10% required for each of them. :)"

"My take was (as I mentioned on an earlier thread) that Cameron looking at that single piece of Coltan was a deep moment to me. It seemed like Cameron was curious. Curious of her beginning. Curious of her birth. Examination of one's self... her self... as much as a learning computer can do at that point anyway.

"It is a common literary theme in scifi to humanize robotic/machine characters. I believe the writers are following along in the same steps, hence the subtle touches they have added to Camerson's character. If she was just a Terminator the audience would not relate to her as they do."
