I think we might lose public key cryptography

Matthew Green, a cryptography expert, expressed concerns that public key cryptography may be compromised due to the increasing computational power of quantum computers. He believes that a quantum computer with 2^32 RSA-2048 operations per second could break RSA-2048 encryption, which is commonly used for secure online transactions. Green also stated that the development of quantum-resistant cryptography is crucial to ensure the security of online transactions and communication in the future.
