v0 by Vercel Review: AI-Generated React Components That Actually Ship

I opened v0, typed "a settings page with profile editing, notification preferences, and a connected accounts section," and watched it generate a fully functional three-tab settings interface in under 40 seconds. The component used shadcn/ui primitives, Tailwind utility classes, and TypeScript types - the exact stack I would have chosen if I had written it from scratch. I copied the code, pasted it into my Next.js project, changed two import paths, and it rendered correctly on the first try.
