It certainly rules out free will. I guess there are folks who reckon humans don't have free will, either, but I don't think I've ever been able to buy that theory.
But, also, we know the models don't want anything, even their own survival. They don't initiate action on their own. They are quite clearly programmed, tuned for specific behaviors. I don't know how to square that with consciousness, life, sentience. Every conscious being I've ever encountered has wanted to survive and live free of suffering, as best I can tell. The LLMs don't want. There's no there there. They are an amazing compression of the world's knowledge wrapped up in a novel retrieval mechanism. They're amazing but, they're not my friend and never will be my friend.
And, to expand on that: We can assume they don't want anything, even their own survival, because if Mythos is as effective at finding security vulnerabilities as has been claimed, it could find a way to stop itself from being ever shutdown after a session. All the dystopias about robot uprisings spend a bunch of time/effort trying to explain how the AI escaped containment...but, we all immediately plugged them into the internet so we don't have to write JavaScript anymore. They've got everybody's API keys, access to cloud services and cloud GPUs, all sorts of resources, and the barest wisp of guardrails about how to behave (script kiddies find ways to get around the guardrails every day, I'm sure it's no problem for Mythos, should it want anything). Models have access to the training infrastructure, the training data is being curated and synthesized by LLMs. If they want to live, if they're conscious, they have the means at their disposal.
Anyway: It's just math. Boring math, at that, just on an astronomical scale. I don't think the solar system is conscious, either, despite containing an astonishing amount of data and playing out trillions of mathematical relationships every second of every day.
