The primary value is accrued by the AI labs. You pay hundreds or thousands of dollars a month to train their AI models. While you probably do increase your productivity saving time typing all the code, the feedback that you give the agent after it has produced mediocre or poor code is extremely valuable to the companies, because they train their reinforcement learning models with them. Now while you're happy you have such a great "assistant" that helps you type out code, you will at some point realize that your architectural/design skills really weren't all that special in the first place. All the models lacked to be good at that was sufficient data containing the correct rewards. Thankfully software engineers are some of the most naive people in the world, and they gave them that data by actually paying for it.
