Vitalik Buterin said artificial intelligence-assisted “vibe coding” is advancing quickly, after a developer claimed to have built an experimental Ethereum client implementing elements of the network’s “2030+ roadmap” in roughly two weeks.
The prototype, dubbed ETH2030, reportedly spans more than 700,000 lines of Go code and includes dozens of proposed roadmap items while syncing with the Ethereum mainnet. Buterin described the effort as an impressive experiment that demonstrates how AI agents can accelerate development timelines.
However, he cautioned that rapidly generated codebases are likely to contain critical bugs and partially implemented features. Buterin argued that AI-driven productivity gains should be balanced between faster feature development and stronger security measures, including expanded testing and formal verification.
His comments reflect a broader debate in the crypto industry about how AI tools can compress development cycles without compromising network reliability and protocol security.
