This move to X, and subtle reference to money transfer, makes me think about something. Musk never got over being shunned when his payment platform idea was rejected when PayPal was formed. He's still traumatized by that incident and is trying to prove to the world that the idea would've worked.

It's not unlike Trump and his bravado. He tries to show he's successful to spite the groups that rejected him for being an outsider when he was young.
