When the code is shitty it becomes harder and harder for the models to make changes and this grinds progress down to a halt - this has been my experience with “factories” trying them and doing refining steps every few months. I sincerely don’t understand what the people who say they no longer read any code are doing, because it must be somewhat trivial to not run headlong into these issues that stack up time after ti…
Even on personal projects, if I go through a few major features without reviewing the code, I always end up doing massive revisions that steal hours of my time and fill me with rage in the process. I'm not convinced this style of "agentic engineering" saves much time. I guess if I was oblivious to what good code looks like, and didn't care about maintainability It wouldn't bother me so much, but it legitimately has e…
Where LLMs excel is in code-level bugs (as opposed to system bugs, design bugs, architecture bugs, integration bugs, etc).
Talk with an LLM, ask them to rate both code and estimate dev experience based on that code, and you will see what they value: Code that passes all the tests is a 10/10, while a codebase designed with opaque data types, Parse-Don't-Validate for all data, isolated interfaces, a built-for-replacement-not-for-extension philosphy will get a 6/10 because an out of bounds error was found.
IOW, they are very strongly tuned to value code that has no errors which can be picked up by linters or similar, while humans work the opposite way - we very highly value code that is easy to maintain, even if they do have a few errors picked up by the linter.
