Depends on how long you want your data to be private, though. There's no guarantee that the encryption won't be broken in a decade or three. And, even if it's not mathematically broken, increased computing power (quantum?) could make brute-forcing fairly trivial.

We are all doomed if this quantum computer works and can break stuff. I also say never ever ;)

irrelevant to symmetric crypto

Not irrelevant, it is my understanding that it can still cut the effort required considerably.

If you are using only a 128-bit key, a quantum computer can cut the brute-force effort required to 2^64, which is feasible today.
