I read a book about 20 years ago about a computer that used pantropy to colonize worlds with modified humans. I think that the purpose was to ensure that humanity would not go extinct. What I remember is that the one of the characters in the story was a girl that had a socket in her head and had to be pregnant in order to function.
The characters were on a quest to find the control room of the computer so that they could bring it back under control. When they did find the computer, the girl directly interfaced with the computer via the socket in her head.
