Scaring the man who survived multiple attacks on his life with AI safety concerns is a lost cause. He is proud of not being afraid. It is against his brand.
The only way you can win him over, is by promising him greatness, heaping lavish praise on him. If you agree with that, you can predict the next set of moves in this game (bookmark this, so you can come back).
But, it is a multi-player game, so winning him over is not guaranteed. Other factions in the palace are equally powerful.
