What would it actually change if Musk was? He already has almost infinite money in practical terms. Is that the crossover point where he levels up and can now buy entire nations? Where he prestiges into divinity and people will enslave themselves to be in his presence?

They treat him like he is the only uber rich guy involved in politics, when the only difference is he is too autistic to be subtle about it. Which means we actually know what he is usually up to and can bully him into exploding about it.

The other ultra billionaires can't even be named without people accusing you of antisemitism, conspiracy theories, or people treating them like Gods (see the glazing of Gates in this very article).
