Sounds pretty good so far.

Its kind of interesting to think about sex/gender when it comes to robots. There really is no reason for them to have a specific sex or gender - biologically I mean. The only purpose of having such aspects would be to make humans feel more comfortable in their presence. It makes them more human like by making them more familiar and/or recognizable. Its interesting that we want to create something new - but in our own image. Why do they even look like humans at all? Would there be a better, more efficient form they could have? These are things I wonder.

Anyway, great story so far. I look forward to seeing where the story goes :)
