🎙️ How I AI: Claude Fable 5 review & How Braintrust uses AI agents, evals, and CI to ship better software

Practical quality beats theoretical quality every time. In theory, a human engineer with infinite time and focus might produce better code than an AI agent. In practice, humans lose context over days, have decaying attention spans on hard-but-tedious problems, and skip benchmarks they know they should run. AI agents maintain consistent focus, run every test, and can work on problems continuously for days or weeks.
