No it’s a given that some people who attempt to wield AI will be adversarial.
In any case a similar argument can be made with merely instrumental goals causing harm: “I am an ant and I do not see how or why a human would cause me harm, therefore I am not in danger.”
People wielding AI and destroying humanity is very different from AI itself, being a weird alien intelligence, destroying humanity.
Honestly if you have no examples you can't really blame people for not being scared. I have no reason to think this ant-human relationship is analogous.
And seriously, I've made no claims that AI is benign so please stop characterizing my claims thusly. The question is simple, give me a single hypothetical example of how an AI will destroy humanity?
Sure, here’s a trivial example: It radicalizes or otherwise deceives an employee at a virus research lab into producing and releasing a horrific virus.
The guy at Google already demonstrated that AIs are able to convince people of fairly radical beliefs (and we have proof that even humans a thousand years ago were capable of creating belief systems that cause people to blow themselves up and kill thousands of innocent people).
P.S. I was not characterizing your opinion, I was speaking in the voice of an ant.
