I appreciate the spirited debate and I agree with most of it - on both sides. It's a strange place to be where I think both arguments for and against this case make perfect sense. All I have to go on then is my personal experience, which is the only objective thing I've got. This entire profession feels stochastic these days.
A few points of clarification...
1. I don't speak for anyone but myself. I'm wrong at least half the time so you've been warned.
2. I didn't use any fancy workflows to build these things. Just used dictation to talk to GitHub Copilot in VS Code. There is a custom agent prompt toward the end of the post I used, but it's mostly to coerce Opus 4.5 into using subagents and context7 - the only MCP I used. There is no plan, implement - nothing like that. On occasion I would have it generate a plan or summary, but no fancy prompt needed to do that - just ask for it. The agent harness in VS Code for Opus 4.5 is remarkably good.
3. When I say AI is going to replace developers, I mean that in the sense that it will do what we are doing now. It already is for me. That said, I think there's a strong case that we will have more devs - not less. Think about it - if anyone with solid systems knowledge can build anything, the only way you can ship more differentiating features than me is to build more of them. That is going to take more people, not more agents. Agents can only scale as far as the humans who manage them.
