IFF an unfriendly AI is already unleashed, we're either doomed, or AIs aren't nearly as dangerous nor useful as we expected. Of course, if we tweak this slightly to them having a boxed unfriendly AI that they're using as an oracle, and which will probably escape via a Trojan Horse or hacking a gatekeeper, it's a much stronger argument.

Bonus points for naming a specific company which people commonly joke will be the first to develop AI :)

Um... I seem to have not yet actually destroyed you... this is embarrassing.
