I feel exactly the opposite. AI has not yet posed any significant threats to humanity other than issues with the way people choose to use it (tracking citizens, violating privacy, etc.).

So far, we have task-driven AI/ML. It solves a problem you tell it to solve. Then you, as the engineer, need to make sure it solves the problem correctly enough for you. So it really still seems like it would be a human failing if something went wrong.

So I'm wondering why there is so much concern that AI is going to destroy humanity. Is the theoretical AI that's going to do this even going to have the actuators to do so?

Philosophically, I don't have an issue with the debate, but the "AI will destroy the world" side doesn't seem to have any tangible evidence. It seems to me that people seem to take it as a given that it's possible AI could eliminate all of humanity and they do not support that argument in the least. From my perspective, it appears to be fearmongering because people watched and believed Terminator. It appears uniquely out-of-touch.
