Andrej Karpathy (AI researcher, OpenAI co-founder, former Tesla AI director) spoke at AI Ascent 2026, Sequoia Capital's annual conference.
What Karpathy said
A year after he popularized "vibe coding" — writing code with AI without diving into implementation details — he says he's never felt more behind: agents now write code faster than a developer can read it.
The next discipline is agentic engineering: an engineering practice where the whole job is steering agents and maintaining output quality, not writing code yourself.
Why it matters
Vibe coding assumed you still read the code — you just wrote less of it. Agentic engineering is the next step: agents work at a volume and pace where line-by-line review is physically impossible. The developer's role shifts from writing to directing.
