Eventual shortcomings will be fixed not by looking into the code, but by typing in another prompt, asking another agent.
Doing it manually will not bring any value to anyone.
I saw it already with my own eyes: a friend of mine started an online psychology counseling site. A year ago they would hire a developer. Now, he only needed an LLM. And it’s the whole thing: a booking system, video calls, a website. What’s underneath: he doesn’t know. The only thing that matters to him is that it works.
That to me looks like the end of programming.
