Addy Osmani shared that at Anthropic, Claude now writes 80% of code and engineers ship 8x more code per quarter — with side effects including 10x test growth and 25x more CI jobs in 6 months. Software luminary Grady Booch pushed back in a quote: 'Shipping more code is a profoundly stupid measure to celebrate. Shipping useful and high-quality features is why we deliver software.' The exchange highlights the growing debate over how to measure engineering output in the AI era.
