Sure. My point is that it's not unusual for the quality of work of a junior coder to be fairly low, and that work typically needs to be double checked by someone more senior before it can be used in production. Often, an LLM will produce a higher quality output than that junior developer in which case, given that the work has to be checked by a senior coder no matter what, the LLM can replace the junior developer.

Also, not every project is highly complex or involves huge codebases and, for those that are, a junior developer might be assigned to a reasonably self contained and small module within the project (i.e. something that a LLM can do better at).

Finally, although this wasn't part of my original argument: before modern LLMs, let's say that a senior developer could produce N units of work per Y units of time. Now, with the help of a LLM, they are able to produce XN units of work per Y unit of time. I don't think it's too controversial to claim that some portion of developers are now more productive than they were before. And if developers in general are more productive, then you can expect some reduction in the number of developers that you need for a given project. So, in an indirect sense, LLMs are already capable of replacing coders.
