Since the gatekeeper is a human, and not all humans behave the same way, shouldn't we just assume that some human would let the AI escape for any variety of reason? For example the AI could promise the gatekeeper that he/she will be rewarded if the gatekeeper lets the AI escape. Just as there are people who fall for Nigerian scam emails, there are people who would let an AI escape from computers when promised riches. I don't think Eliezer needs to reveal his method to show that a clever AI could escape. I think we should just assume that a clever AI could escape.
