Oppenheimer at one point believed that there was some possibility the atomic bomb would set the atmosphere on fire and kill all humans. However, at least that particular fear was falsifiable. Other physicists ran calculations and concluded it was impossible.
Do these beliefs about the dangerousness of AI possess even that quality? Are they falsifiable? No.
These arguments are begging the question. They assume as a given something which cannot be disproven and thus are pure statements of belief.
Problem is, AFAIK the math tells us rather unambiguously that AI alignment is a real problem, and safe AI is a very, very tiny point in the space of possible AIs. So it's the other way around: it's like scientists calculated six ways to Sunday that the hydrogen bomb test will ignite the atmosphere, and Oppenheimer calling it sci-fi nonsense and proceeding anyway.
Please also respond to the main arguments I gave and linked to if you can.
