- Charles Stross: Crib Sheet: Saturn's Children: "Causality violation [is] an unavoidable side-effect of faster than light travel. A side effect of causality violation is that you quite possibly end up with time loop logic, which has some really alarming implications if you can figure out a way to map this onto a human-equivalent or faster AI. The easiest way out of the trap is to adopt the Novikov self-consistency principle and throw FTL under a train. This doesn't totally rule out AI. We have an existence proof for human intelligence as an apparently computational process: it's called the human neural connectome. But it's fiendishly complex, not terribly hackable, and tends to function best when coupled up to an i/o device called 'a human body'."
