I have no idea where most people writing code have worked at but in all product and platform teams I worked at the code quality has been much higher than the latest slop SOTA llms can output.

TLDR: coding is not solved.

I have 2 projects, one it's a distributed platform, the other one is a general processing engine with an inner workflow engine; Since gpt 5.2 I've tried new models to work in these codebases where the code is of good quality and every time I gave the model a slice of work instead of a single step from that slice the code, the tests, the comments, the docs and everything else has been suboptimal, unmaintainable, complex, bloated and just slop, unless I micro-manage and do many passes.

As a dev when you make a change you consider the broad picture, you consider the user, the codebase, future requirements, maintainability, performance, your team's understanding and some of these you do unconsciously. We are slow but that's for multiple good reasons, you push the organization/understanding forward not just loc of that specific project. I can't count how many PR notes or comments I've added considering teammates or just for a specific team member.

I don't see any way forward for an LLM to reach that unless it reaches general problem solving, my definition of GAI that could tackle software development or "coding" would be a model that doesn't require additional pretraining to solve new tasks or improve how it solves tasks in the future, it would just learn as it's going.

Can everything I mentioned be solved with current generation of LLMs and lot's of markdown and gates? Maybe... but the amount of effort required would be similar to the effort an expert system (pre-llm AI) would require to embed the rules, evolve them, check them everytime... which would require billions or trillions of tokens.

off: I really like the discussions around how to prevent slop and bloated code as it's something it would benefit coding even without LLMs and can fit as another piece of automated infra for checking and ensuring code quality, I hope something materializes.
