Vitalik: Bug-Free Code Won’t Be a Myth in the 2030s

Vitalik Buterin believes one of software’s most common assumptions is about to break. According to his recent post on X, the long-standing idea that “bugs are inevitable” won’t necessarily hold true in the 2030s.

His point isn’t that all software will suddenly become perfect. Many applications will still ship with bugs, largely because developers often prioritize speed, features, and experimentation over absolute correctness. But Vitalik argues that when teams genuinely want bug-free code — and are willing to design for it — the tools, methods, and verification systems will be good enough to make that goal realistic.

This view aligns closely with where crypto and blockchain development is heading. As smart contracts increasingly manage real value, governance, and infrastructure, tolerance for bugs keeps shrinking. Formal verification, advanced testing frameworks, and AI-assisted development are already pushing software closer to mathematical correctness.

The takeaway isn’t optimism for optimism’s sake. It’s a reminder that software reliability is becoming a choice, not a limitation — and the next decade may redefine what “production-ready” truly means.
