Yep. I put up this hypothetical before: Drop an iPhone into liquid nitrogen, slice it up very thin. Now recover the icons for the first three entries in the address book.
At least in this case we would expect it to be possible for someone with enough money and time, with today’s technology. You should be able to recover the contents of the hard drive.
The domain-expert (Gutmann) says otherwise. At this stage, it’d really take an example of data recovery in practice, not just in “you can’t prove I’m wrong!” hypothetical.
(I’m assuming you don’t have an example to hand of having recovered data yourself in this manner.)
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.
