A better version of my point is it doesn't need to meet the bar of intelligence to cause almost all the same problems that an intelligence could. Viruses indeed evolve and adapt more flexibly than humans, to where arguably today, the only existential threat humans face comes from biological viruses, which are also not intelligent. We don't need to come up with fun thought experiments to describe what intelligence is when we have enough trouble with the question of, for what is intelligence either sufficient or necessary? Diminishingly little, I'd say. Hence I'd be more concerned about virulent scripts than waiting for general AI.
