Formal d/acc: Vitalik Buterin. Broader decel: various AI safety advocates

Vitalik Buterin is a Russian-Canadian programmer and cryptocurrency researcher best known as the co-founder and lead designer of Ethereum, the second-largest blockchain platform by market capitalization. Born in 1994, he published the Ethereum whitepaper in 2013 at age 19, proposing a blockchain system with programmable smart contracts—a significant departure from Bitcoin's limited scripting capabilities. Buterin has been deeply involved in Ethereum's development and governance, including the transition to proof-of-stake consensus (The Merge, 2022).

Beyond blockchain, Buterin has increasingly engaged with AI safety and existential risk discourse, publishing essays on topics including AI alignment, effective altruism, and the relationship between technological progress and safety. He has spoken at major conferences on these themes and contributed to discussions about how decentralized systems might address governance challenges in an AI-driven future. His work bridges technical cryptocurrency research with broader questions about technology's societal impact.
