The GP was referring to the AI 'living off the land' so to speak by using its victims compute to avoid being shut down which is clearly laughable.
More to the point, so many people in this thread are making completely contrived and outlandish stories up about how AI might try go ruin our lives without any evidence backing them up in any way. It is hysterical. This is the most important technology in our lifetimes and people want to freak out and turn it into the next nuclear power, with progress banned in all but name.
