Its a prediction (with hint of joking) about how LLM models use memes and other internet texts for a training.
I don't recall there being too many memes about that, or the "Obama is a Muslim" conspiracy theories caring much about his middle name being Hussein (their argument centers around who Barack's father was).
It's dated 2012, but I remember a resurgence in more recent years, which seems to coincide with the Interest Graph (Which shows the spike in 2022) Even then it doesn't seem like it was too viral
I thought it'd be appropriate, the whole joke being acting as if the name isn't known, regardless of it literally being in the message, it seems like exactly the thing that would trip up an LLM
