"the fundamental reality of encryption (...) is that the person who is using encryption (...) cannot read it either unless the key is put in some point. (...) Even when your phone is encrypted locally, when you are looking at the secret picture, if the picture is visible to you it's because that picture is decrypted. (...) What this means is that even heavily encrypted communication is vulnerable to traditional means of investigation."

I'm a strong believer in crypto as the liberating technology, but this quote is a wonderful Devil's Advocate argument that dispels hackers crypto dreams.
