Critique: Bend 2's AI-verification language demands hundreds of lines for simple proofs

A blog post examines Bend 2, a programming language designed for an AI-assisted workflow where humans write 'laws' and AI writes implementations plus formal proofs that a compiler checks. Using Bend's own homepage demo as an example, the author notes that stating a simple game rule takes 58 lines of code, while the AI-generated proof of that rule balloons to 442 lines. The piece argues this ratio illustrates a broader vibe-coding pitfall rather than being unique to Bend.
