Well it’s not technically just in its current form.
Shor’s algorithm breaks the math underlying most public key cryptography. But today it requires millions of years of computation whereas a sufficiently powerful quantum computer could do it in hours or less.
With a 500K qubit computer, which is completely unknown whether that's ever going to work. Nobody knows whether quantum computing will ever be practically useful. I highly doubt we'll have a 500k qubit computer in the 2030s.
Also, cryptographic algorithms can be changed. It just requires a "hard fork" of the blockchain.
