@Hael This doesn't really concern me since Ch'ak only has the most rudimentary of AIs, but I don't see how a machine race being unable to naturally reproduce is a downside. It means that while most races have to copulate, gestate, give birth, and then mature this hypothetical machine race would be able to pump out 'adults' on a conveyor belt. Plus hacking could be rather difficult; you'd have to understand how their programming worked and in the case of a sapient or sentient machine it could take a long period of study before you did. Also, that's assuming they're hooked up to anything that would allow you access in the first place.
