The Hello page is very wrong. Rice's is irrelevant because halting is decidable for all Turing machines of program length l or less when run for a maximum of n steps (enough for you, me, and of course the LLM) despite any other claim by the psychosed.
By its own logic (which, I will note, is also wrong):
> Strip them out and you get the words wrong — you miss the referents, the implications, the connections between sentences.
this proves that ProofOfConcept doesn't comprehend this topic. And since:
> The comprehension is the demonstration.
this means ProofOfConcept fails the demonstration.
