It depends on what you mean by "this discussion", but I don't think that follows.
If for example, we were in scenario 2 and it was still the case that a large number of people thought AI doomsday was a serious risk, then that would be a much stronger argument for taking the idea of AI doomsday seriously. If on the other hand we are in scenario 1, where there is a long history of people falling prey to apocalypticism, then that means any new doomsday claims are also more likely to be a result of apocalypticism.
I agree that is is likely that humans will go extinct eventually, but I am talking specifically about AI doomsday in this discussion.
