I know. And I say that "there is no such thing" in the sense of it having a meaningful impact on the outside world. It's solely something for the inventor in private to be happy or sad about. There isn't even a point in telling the world their intention. That's like telling the desert to be green and thinking you did something.

Yes. Partly anyway, of course the main fault is always with people "pulling the trigger". For the reasons laid out above. Weizenbaum couldn't possibly spell it out more clearly, and your response was basically giving an example for what intent is. We know, the response is that it's a fallacy. To just repeat the original thing doesn't change the response to it.
Maybe you misunderstood what I was trying to say?
I was not talking about the inventions themselves but the intent of the inventor
Sometimes a person (or organization) sits down and says "I want to accomplish <goal> so I am going to put resources towards finding a way to do that"
<Goal> can be anything from "a new way of preserving apples" to "a way to kill a whole bunch of people at once"
If it turns out that your new way of preserving apples also can be weaponized, is that really your fault for inventing it? That doesn't seem right to me.
Otherwise the only moral action is to not invent anything? Absurd.
