Ever wondered what Vitalik Buterin’s most worried about for the future of Ethereum?
During a recent AMA on Farcaster, one user asked just that, to which the Ethereum co-founder responded: “The risk that crypto stagnates, things like privacy and open internet infrastructure become lost causes.”

A bot-laden Internet may also become the driving force behind regulatory policy in tech is the rise of smarter and smarter AIs.
Instead of the decentralized ideals that have inspired crypto, he said he’s concerned that “the big techno-political questions of the 21st century just get decided by whatever happens in AI over the next decade.”
Still, Buterin shared praise for decentralized social media platforms built using Ethereum sign-in options like Farcaster and Lens Protocol.
He replied to an AMA question saying, “I do hope that Farcaster and Lens and co become as big as Meta one day!”
