That's the innovation of bitcoin. Lot harder to break SHA256 ;-)

  Do you really believe we will be (profitably) bringing gold back from asteroids before a quantum computer is developed?

    Quantum computers isn't going to break hashing. https://en.wikipedia.org/wiki/Post-quantum_cryptography https://en.wikipedia.org/wiki/Post-quantum_cryptography >In contrast to the threat quantum computing poses to current public-key algorithms, most current symmetric cryptographic algorithms and hash functions are considered to be relatively secure against attacks by quantum computers

    Not sure. I don't think quantum computer would necessarily break bitcoin encryption. I don't think it would come out of nowhere, but if it were to happen, I think there would be a hard fork to change the algo to one that is quantum secure (such algorithms do exist). I have more faith in the organization capabilities of the Bitcoin core developers especially with so much wealth at stake. Compare that to a gold supply shock. You'd have to get a lot of participants and organization to designate an alternative metal as defacto store of wealth. But bitcoin is superior to all of them in terms of verification and fixed supply, so I think they would come over to the dark side as well
