Karpathy hasn't written code by hand in half a year: in December he started using the latest coding agents, and within a few weeks he was barely correcting what they returned. The agents type, he supervises.
Karpathy is an OpenAI founding member, led Tesla's Autopilot AI team, has run Anthropic's pretraining research since May, and coined the term vibe coding in early 2025. When he says on the Sequoia stage that he's never felt more behind as a programmer, it isn't about syntax. The default work shifted from writing code to overseeing it.
What a developer does now
The programmer is no longer a code writer but a conductor. You supply the spec, agents write it, you supervise. Taste, security, system-level decisions stay with you.
His example is a MenuGen bug: the agent tied the Stripe email to the Google login email. Plausible code, broken system design, because the two emails can differ. The human move was to require a persistent user ID, since identity doesn't ride on email.
He calls this real engineering. Vibe coding raises the floor for everyone; anyone can put something together. Agentic engineering raises the ceiling for whoever is responsible for what ships. The old "10x engineer" is no longer the ceiling.
Where he's careful
The AI isn't a human mind. Karpathy's framing: we summon ghosts, we don't build animals. No motivation, no curiosity, no inner attention. A statistical simulation shaped by pretraining and RL. Brilliant one moment, strikingly dumb the next. He calls it "jagged intelligence."
On verifiable tasks (code, math) the models fly. Off them (taste, common sense) they stumble. AGI is still a decade away, not a year. Today's agents aren't interns; they only approximate one.
As he puts it: "you can outsource your thinking, but you can't outsource your understanding." The typing is delegable, the understanding isn't. What to build, why, and when its answer is wrong: you can't hand that off.
What I see building Phora
Karpathy's framing fits what I see building Phora. The agents behave like interns: fast, tireless, occasionally off at the system level. Spec, oversight, taste aren't new skills. Generalists have always done them.
Now more of it fits inside one person.
There's always a next level.
If you like what you see (whether you're building a product or a team) I'd love to hear about it.
