The only part that really choked me up is when they were reading, at the end, of discovering the body of a girl with her parents. Uhhh. The use of 'girl' is making me think that Hera didn't survive childhood. I then suspect a harsh winter with food die-off. Since we know her parents would cut their arms off before allowing her hurt I have to imagine they all died around the same time. Within a year or two of arriving.

And if it can happen to them then it obviously could happen to many others. Which is tragic, to me.

Also, I have to wonder if they hadn't decided to start with a fresh slate, but instead dedicated their technology to maintaining an accurate history (ie, not the scrolls of Pithia ) they might have avoided the whole enslaving of robots mess that is apparently our greatest weakness.

But maybe I'm giving this too much thought?
