Why? We don't need Bitcoin to be quantum proof for now because there's no actual quantum computer in our age. Google claiming that they have quantum supremacy doesn't mean anything to Bitcoin. They might have the fastest computing computer but it still will won't affect the security of Bitcoin.
Yes,,, people are making a huge fuss about something that does not even exist. If a quantum computer somehow for some reason breaks bitcoin,,, that will be the day they will use it to break something else. 1000s of other things more sensitive than Bitcoin have weaker security. Try hacking bank databases. Probably do not even need quantum for that!
