Agreed. My overall / initial point was that I can’t say the time to crack = the time to brute force and start talking about the age of the universe. 10,000 years is a blink of an eye in that timescale.

Quantum cryptography is most helpful in detecting eavesdropping (due to the no clone theorem). Quantum cryptography is helpful in avoiding asymmetric encryption for key exchange when communicating with symmetric encryption. Eg BB84. And given asymmetric encryption is most vulnerable to quantum attacks (compared to symmetric), quantum cryptography improves today’s state of the art. BUT, I insist that none of this gives provably uncrackable schemes.
AND it might be that we never build such a scheme. After all we have Godel’s incompleteness theorem lying around.
