> OP is saying that beliefs inspire action, but as of now we haven’t seen action from these people that support such an extreme belief.

That something is harmful to humans means you need to take extreme action? The person is already leaving a job, probably a well-paid one, doing something they generally liked, until they saw a different future. That is the "action" you apparently haven't seen yet.

Not sure how it's reasonable to expect everyone who believe that AI might be involved in killing people in the future, must mean you should become a terrorist essentially. Not everyone is trying to be a hero in their life, some just want to live it out until it ends, trying to survive until then.
