I guess I've been pronouncing it wrong though. It's wave function collapse, not waveform.
I haven't studied it properly yet but it kind of looks like how sudokus work. You have a bunch of plausible options, and the various possible worlds overlap with each other but not completely and then you eliminate the things that are not possible until the actual possibility remains.
I think thinking works similarly, and I wouldn't be surprised if artificial thinking also worked similarly.
Quantum waveform collapse has been proposed as explanation for consciousness, allowing to explain how an entity can have free will and yet obey rigid physical laws: https://en.wikipedia.org/wiki/Consciousness_causes_collapse
I think OP is suggesting a similar thing happened in the LLM, implying it gained consciousness despite following a well-defined compute process.
