Vitalik: Quantum computing mainly threatens cryptographic signatures rather than consensus mechanisms and will not cause a 51% attack on Ethereum.

Exclusive from Foresight News, when asked whether the development of AI and quantum computers would cause a 51% attack on Ethereum, Vitalik responded, "I don't think so. We need to clarify the concept: the essence of a 51% attack is to attack the consensus and coordination mechanism of the PoS (Proof of Stake) system—which requires controlling 51% of the total funds on the network, not computing power. Quantum computing mainly threatens cryptographic signatures, not the consensus mechanism; as for AI, I believe it is not a threat, but rather can provide assistance. For example, AI can help us with formal verification and discovering code vulnerabilities, thereby making Ethereum more secure."
