Maybe. The reality of software engineering is that there's a lot of mediocre developers on the market and a lot of mediocre code being written; that's part of the industry, and the jobs of engineers working with other engineers and/or LLMs is that of quality control, through e.g. static analysis, code reviews, teaching, studying, etc.

The "most engineers" not "most engineers we've hired".

But also "most engineers" aren't very good. AIs know tricks that the average "I write code for my dayjob" person doesn't know or frankly won't bother to learn.
