Looking through their post history they are either non-native English speaker who is a bit of a polymath but without the actual math part or an LLM someone is having fun with reusing a prompt they devised or copied.
At least their language and tone are constant across posts, albeit a bit inscrutable. FWIW, I did get the dark humor in their/its post.
I see no cake. Then again, I am not a particularly observant human. It’s not one of the/both umbrellas, right? That’s their cool name, yes?
(Probably I’ve monkeyed with my settings and it just doesn’t show for me.)
