Will it start a war?
I hope that they include in the code whatever recommendations come from the United Nations Office of Outer Space Affairs (UNOOSA) guidelines.
It would be a shame if it decided to do something (change course?) that was then interpreted as an attack by an alien civilisation, and they returned the favour by launching a battle fleet. I have two small dogs and they already have trouble with their guts, thank you, without having to swallow the arriving battle fleets.
P.S. to those above, we used to do AI on quite puny computers back in the '80's, you just have to be careful with the code.
