It's such a show of his tiny baby brain that Elon keeps fucking up his alt posting. Like, he could have his own device per account. He could pay a guy to make sure he is on the right account. He owns the platform and could have his own UI for this shit.
But it's just not a thought, because he himself thinks he's too smart to ever fuck up and the MANY MANY examples that show otherwise are just banished from his mind. The billionaire mind is not human.
