Couldn't you Ender's Game a model? Models will play video games like Pokemon, why not Call of Duty? Sorry if this is a naive question, but a model can only know what you feed it as input... how would it know if it were killing someone?

EDIT: didn't see sibling comment. Also, I guess directly operating weaponry is different to producing code for weaponry.

I guess we'll find out the exciting answers to these questions and more, very soon!
