A possible example: an AI is not aligned about the amount of energy it will consume, and after each iteration of self-improvement, it consumes 10 times more, starting from 1 watt. At first 10 stages it will be not a problem, but after its consumption will become 10 Gigawatts, it clearly becomes a problem, and at 10 Billion gigawatts it is a catastrophe.
