At the OKX NOW launch event, Vitalik said that over the past five years, AI has meaningfully accelerated many things. AI is both the greatest opportunity and the greatest risk. It is already helping the Ethereum protocol identify vulnerabilities and implement highly complex forms of cryptography. He believes AI will become the new user interface, eliminating the intermediary layer between blockchains and users. As AI advances, blockchains will face more and more challenges—just like other areas of the internet. Blockchains will encounter these challenges first because funds are concentrated in the blockchain world. He expects privacy technologies such as zero-knowledge proofs to mature rapidly over the next two years, with transaction costs becoming much lower than they are today and a greater emphasis on privacy.
