I'm inclined to think that you have to get down to the technical nitty-gritty. If you don't know the field, it might be reasonable to think that in the future we'll prove that our ciphers are unbreakable. Actually, for everyday useful ciphers, a proof that they are secure with no unproven assumptions is much harder than you might think if you've not studied CS. There's no reason I'd expect you to know that if you're not a computer scientist, but if your vision of the near future included provably unbreakable ciphers, I'd want to explain why that doesn't look very likely at the moment.
What do you think?
