I mean, I can imagine an AI outliving humans, with sufficiently good robots under its control, I see no reason why an AI could not keep powerplants running, mine raw materials, manufacture new chips, and so on. But the timeframe of within the next decade seems highly implausible to me. Imagine an AI way more advanced than what we have now and imagine handing over control of every connected device on earth, could the AI keep the lights on without any human involvement?
