So really not to worrisome. Quantum is the real danger.
Quantum is no danger.

Is the encryption used by VeraCrypt vulnerable to Quantum attacks?
VeraCrypt uses block ciphers (AES, Serpent, Twofish) for its encryption. Quantum attacks against these block ciphers are just a faster brute-force since the best know attack against these algorithms is exhaustive search (related keys attacks are irrelevant to our case because all keys are random and independent from each other).
Since VeraCrypt always uses 256-bit random and independent keys, we are assured of a 128-bit security
level against quantum algorithms which makes VeraCrypt encryption immune to such attacks.

I think the algorithms used in Monero are even stronger than in VeraCrypt.
Quantum attacks are potentially a danger to Monero. The distinction is that symmetric encryption like AES, etc. are much less vulnerable than signatures. All widely-used signature algorithms including those in Monero and Bitcoin are potentially vulnerable. It will be something that cryptocurrency will need to deal with in time but no one is panicking quite yet.
then its a good thing Monero has a hardfork schedule in place, I assume it could be invoked in emergencies such as an indentified quantum attack is in place and a known remedy can be implemented.
