If it ends up that 40 years from now quantum computing can beat all present-day encryption methods, would the bitcoin price instantly just go to zero? Is there anyway to retroactively make it more secure with tomorrow's cryptography?
EDIT: I only ask this because if the world becomes more and more dependent on the blockchain and quantum computing becomes an existential threat, the existence of blockchain-breaking computation could potentially result in a global catastrophe. I compare quantum computing in this scenario to a device that can just magically take money away from you without your knowledge. Given that this obviously hasn't happened yet, I'm curious what mitigation strategies exist now. Thanks everyone for your replies.
disclaimer: I believe it's just a matter of time before all current (2021) encryption is broken. whether that happens in 2060 or 3000 obviously is TBD, but it's a matter of when not if IMHO.
