One guy. Three hours. A flight simulator, built inside a browser. Pieter Levels prompted Cursor and Grok to build from scratch, vibe coded almost entirely live on X. 17 days later: $87K a month. 320,000 people dogfighting strangers online. Elon Musk tweeting about it. The money came from ad slots on the terrain, zeppelins, billboards, about $5K a pop, sold straight from his own account. No team. No pitch deck. Just a guy shipping alone with tools most of us already pay for. This is what solo looks like now. #buildinpublic
