First of all, you have to understand not only bitcoin is at risk — our ENTIRE life is dependent on the same math that assumes bitcoin is not hackable. So if there is something able to hack bitcoin, then we anyway have MUCH bigger problems and bitcoin is itrelevant

Second, quantum computing is a myth. Quantum resistant algos is a myth. They do not exist. There are even no working theories. There are a couple of math theories and some practical experiments in this area but its just scientists having fun. Today, even if something like this gets developed, nobody knows will it be more efficient at hacking bitcoin than an ASICS fleet or less efficient. Nobody knows how those quantum algos (to attack and to defend) would look like. Thats all speculations

Indeed, its an extremely interesting area of science which has a chance to change our lives significantly in future. But today its probably less real than flying cars back into 1960x
