There are plenty of algorithms that quantum algorithms give no benefit to. Quantum is NOT a free for all making everything faster. It’s only faster at two very,very restricted things: hidden subgroup problem (which is used for RSA, but most problems do not rely on HSP), and Grover search, which reduces a specific search problem from O(N) to O(sqrtN).
