DHH, the creator of Ruby on Rails, argues that directing coding agents increasingly depends on defining the desired product. In his conversation with Lex Fridman, he describes moving from prescribing implementation steps to describing problems and letting the AI agentAn AI system that doesn't just answer once but works toward a goal in a loop — taking actions, reading the results, and deciding what to do next.Full definition → choose a solution.
His account places emphasis on product judgment: what the software should do and who it is for.
