There's an idea used in crypto commonly called "reasonable security". Anything is possible given an computationally unbounded adversary, but the point of strong crypto is to make it such that cracking the crypto takes an "unfeasible amount" of time. Crypto isn't some spectrum like waterproofing is, it's binary: either broken or it's "will be broken".
