I think human developers can architect and design better software, and a good developer will probably develop features better as well. The issue is that "better" here is not immediately obvious. It might take a few months to realize the "way" the code was written is causing problems. Some people might never even realize this and just assume that's how all software is, it just breaks down over time (which is obviously not true, lots of decade old software and languages exist). But if the company is ok with rewriting their code every few months, then it makes no difference.
