I don't see any proof that software development is not dead. Software engineering is not, and it's much more than writing code, and it can be fun. But writing code is dead, there is no point of doing it if an LLM can output the same code 100x faster. Of course, architecture and operations stays in our hands (for now?).
Initially I was very sceptic, first versions of ChatGPT or Claude were rather bad. I kept holding to a thought that it cannot get good. Then I've spend a few months evaluating them, if you know how to code, there is no point of coding anymore, just instruct an LLM to do something, verify, merge, repeat. It's an editor of some sorts, an editor where you enter a thought and get code as an output. Changes the whole scene.
