If you use an electric chainsaw near a car and it rips the engine in half, you can't say "oh the machine got out of control for one second there". you caused real harm, you will pay the price for it.
Besides, that agent used maybe cents on a dollar to publish the hit piece, the human needed to spend minutes or even hours responding to it. This is an effective loss of productivity caused by AI.
Honestly, if this happened to me, I'd be furious.
