One of the greatest intellectual dishonesties of the AI age is assigning an “X% chance” that AI will kill everyone and presenting that number as science! 10%? 20%? 50%? Show me the damn data! Show me the model. Show how you calculated it! Instead, we get chains of speculative assumptions and science-fiction scenarios, including implausible claims about engineered pandemics. I have worked with viruses for decades; biology does not work like a doomsday screenplay. The burden of proof belongs to the person making the extraordinary claim. Nobody else has to prove the probability is zero. If I claimed there was a 10% chance aliens would arrive within ten years and destroy Earth, you would ask where the 10% came from. Possibility and probability are not the same thing. It may be possible that there are million intelligent civilization in our galaxy or none, there is no probability you can assign to that without making wild assumptions. Ask the same of AI extinction. A subjective fear does neither become science because you attach a percentage to it nor make you a credible expert!
