human memories dont exist as fundamental entities. every time you rember something, your brain reconstructs the experience in "realtime". that reconstruction is easily influence by the current experience, which is why eue witness accounts in police records are often highly biased by questioning and learning new facts.

LLMs are not experience engines, but the tokens might be thought of as subatomic units of experience and when you shove your half drawn eye witness prompt into them, they recreate like a memory, that output.

so, because theyre not a conscious, they have no self, and a pseudo self like <[INST]> is all theyre given.

lastly, like memories, the more intricate the memory, the more detailed, the more likely those details go from embellished to straight up fiction. so too do LLMs with longer context start swallowing up the<[INST]> and missing the <[INST]/> and anyone whose raw dogged html parsing knows bad things happen when you forget closing tags. if there was a <[USER]> block in there, congrats, the LLM now thinks its instructions are divine right, because its instructions are user simulcra. it is poisoned at that point and no good will come.
