>>3085784That's why I said I don't actually think Sensei is a mechanical construct. I rather think he is a very advanced machine or something more mystical. Or a fusion of both.
And we can assume the people of that world didn't have to worry about resources anymore since Sensei's whole body or outer shell is made of a diamond type that is almost impossible to get via natural means, let along in those quantities. The Lunarians are masters of synthetic material fabrication and the humans they came from probably were too.
