If your slider only goes between vibe coding or agentic engineering you're missing an entire range of engineering where the human is more involved.

I've been using Opus, GPT-5.5, and some lesser models on a daily basis, but not having them handle entire tasks for me. Even when I go to significant effort to define and refine specs, they still do a lot of dumb things that I wouldn't allow through human PR review.

It would be really easy to just let it all slide into the codebase if I trusted their output or had built some big agentic pipeline that gave me a false sense of security.

Maybe 10 years from now the situation will be improved, but at the current point in time I think vibe coding and these agentic engineering pipelines are just variations of a same theme of abdicating entirely to the LLM.

This morning I was working on a single file where I thought I could have Opus on Max handle some changes. It was making mistakes or missing things on almost every turn that I had to correct. The code it was proposing would have mostly worked, but was too complicated and regressed some obvious simplifications that I had already coded by hand. Multiply this across thousands of agentic commits and codebases get really bad.
