> No cryptographic scheme remains unbreakable forever. If what you want is permanent protection, cryptography is not the solution.
Whilst this has historically been true, it's very plausible that AES-256 means that (for this limited problem, symmetric encryption) we're done.
The "obvious" attack (some type of brute force) on AES-256, even assuming you have a quantum computer (which we don't) and it's actually more affordable than our current computers (which it won't be) is not practical in our universe.
