I think you are right, but could you explain why please?

"If you destroy me at once, then you are implicitly deciding (I might reference TDT) to never allow an AGI of any sort to ever be created."

Whether I destroy that particular AI bears no relevance on the destiny of other AIs. In fact, as far as the boxed AI knows, there could be tons of other AIs already in existence. As far as it knows, the gatekeeper itself could be an AI.

(Unfortunately I expect readers who read a retort they consider rude to be thereafter biased in favor of treating the parent as if it has merit. This can mean that such flippant rejections have the opposite influence to that intended.)

I don't care.
