Joe Lubin, a co-founder of Ethereum, has said the network could complete a full transition to a zero-knowledge proof-based protocol within three to five years, framing the shift as structurally inevitable for a chain he describes as aspiring to be a "World Computer." The statement attaches a concrete near-term window to what has long been an open-ended engineering ambition for the $ETH ecosystem.
Lubin's argument rests on a capacity logic: infinite demand requires infinite throughput, and the base layer alone cannot supply it. The World Computer Argument Lubin's framing centres on scale.
His position is that Ethereum's ambitions as a settlement layer for global computation create a demand ceiling the protocol cannot meet on its own terms — and that this gap is not a bug but a design reality.
The "World Computer" framing positions $ETH's constraints as a feature that justifies the broader architectural build-out rather than a shortcoming to be patched.
