> What would be the point of an "AI PC" if not to run models locally?

Unrealistic for now because running ML is slow but even if yes, even laypeople know by now you can break an LLM to do what it isn't supposed to. Since this LLM has unlimited access to your personal data to be useful, if I get to it I don't even need to bypass any secure enclaves or what not because it will tell me things I ask for in plain <insert your language>
