Description

His company policy is: there will be absolutely no human-written code. Today, we're talking to Trevor Hinesley, Cofounder and CTO at Soundstripe. We discuss the five levels of AI-written code and what it actually looks like to operate at the highest ones, why Trevor's team has a strict policy of zero human-written code, how the "dark factory" concept is reshaping what engineers actually do, and why a company built on AI-powered development still bets everything on human-made music.
