Dave Goldblatt showed off HackerTube, a YouTube-style site restricted to videos repeatedly recommended on Hacker News over the years (Ben Eater's USB keyboard explainer, Bret Victor's 'Power is not energy,' etc.). Andrej Karpathy revealed he built it with a single prompt to Claude: 'Hi Claude good morning... build me a YouTube-style site but restricted to videos that have been repeatedly recommended on HN over the years pls. Don't make any mistakes.' Asked if it's open source, he reposted with 'there is no moat' — a weekend-level vibe coding demo underscoring that coding moats are gone.
