It's just another case of Musk trying to sound smart but instead ends up proving that he doesn't even have a basic working understanding on the subject.
I guess this time the only difference is that it doesn't look like he paid an actually competent person to help him with it.
This might be giving him too much credit, but I think what he's trying to say is that he had the woke_mind_virus and deleted it from his mind? They've all co-opted the term red pill from the Matrix (widely seen as a trans allegory) and are using it to justify their unpopular actions because they're now free of having to be "woke" and can oppress those who are marginalized.
