Machine reproduction is an interesting concept because it is highly dependent on the previous topics of Genome and DNA sequences. At some point the machine must become male, female, both or neither.
Machines are only somewhat Hermaphrodite in nature as they can do self cloning. Self cloning only produces an exact copy of the original and does not produce an intermixing of genome for genetic diversity and evolutionary purposes.
It would make more sense to send one Brain to the Moon and have it replicate itself rather than initially send two brains, one male and one female. This saves expense and weight.
This is the pattern of the initial Big Brain. Later, Big Brains will require sex, Male Big Brains and Female Big Brains - to ensure the mixing of DNA and evolution.
There is a difference in reproducing and creating genetic diversity. Genetic diversity is achieved when two snails mate together.
