It would be cool to have a beer, or beverage of your choice, and talk about this!
I've worked as a Software Engineer in an AI lab for a military contractor so this is of great interest to me. I have my own designs for self-replicating machines, and I can see how your scenario could play out. Maybe someday I'll put my AI and self replication writings on here, and perhaps you'd be able to morph some of them into ideas for your most excellent sci-fi fiction short stories.
Too late. There's also this one, and a full length novel I'm releasing soon. By all means share your writing though. Information sharing only gets us where we're going faster.
