I read Gutmann as talking about what you should expect, security for the real world. I don’t see where they talk about someone willing to put in an unrealistically huge amount of effort. But maybe I missed that? Could you point me that way?
It is true that I can’t philosophically prove that arbitrary hypothetical technology that would achieve something currently nigh-equivalent to magic cannot possibly exist, nor can I philosophically prove the data isn’t there any more, yes. I can say there is no evidence for either, and expertise and evidence against both, and that “but you can’t prove it isn’t true!” isn’t a very good argument.
