He has zero self-awareness. When Elon found out that his then-girlfriend, Grimes, was going to voice a character in the game Cyberpunk 2077, Elon showed up at the developer's studio, unannounced, requesting that they make a character for him to play the voice of, too.
Nevermind the fact that Cyberpunk 2077 is a game about fighting corrupt billionaires and their mega-corporations large enough to employ their own private armies and instate their own governments, the leader of which wants to live forever by means of transferring his consciousness into a chip that can be implanted into a brain. Elon recognized absolutely none of the irony in the situation. Never once did he realize he was already in the game, except they named him Saburo Arasaka.
