Will AI replace software engineers?

The builders of AI coding tools describe a change in the job, not its disappearance. Andrej Karpathy calls the new unit of programming the text you hand an agent; the emphasis shifts to defining what to build, taste, and clear goals rather than writing every line.

What is 'software 3.0'?

Andrej Karpathy's term for programming by instructing an intelligent agent in natural language, instead of precisely spelling out every detail in code. The agent looks at your environment and fills in the implementation.

How is AI changing product timelines?

Cat Wu, Head of Product for Claude Code, says feature timelines have dropped from six months to one month, and sometimes to one week or even one day, so the PM's job becomes shortening the time from idea to shipped.

Are PRDs dead in the age of AI?

The OpenAI Codex product lead Andrew Ambrosino argues no. Even though cheap implementation tempts teams to jump straight to prototypes, he explicitly disagrees that 'PRDs are dead' — the thinking still matters.
