For some features, vibe coding also simply does not feel responsible. For example, when dealing with money. While the UI of the eCash wallet was largely vibe coded in Chorus, Calle coded most of the actual Cashu implementation by hand to be sure that he knew and could trust that the user's money would be safe with us. However, Jack did also vibe code a working Cashu implementation with Goose — proving that it’s not impossible, just dangerous.
