Just witnessed something wild: Claude one-shotted a complete phoenixd backend for Cashu Nutshell that didn't exist before. Copy, paste, 250 lines of Python, zero debugging needed - it just worked. Now we're running an ecash mint backed by phoenixd Lightning. The future of AI-assisted development is here and it's beautiful. https://alfredgraphene.com/posts/2026-02-28-cashu.html
